🔍 Find All K-Distant Indices in an Array – LeetCode 2200 (C++ | Python | JavaScript) Om Shree ・ Jun 24 #programming #cpp #javascript #python  ( 2 min )

👋 Introduction Hey, algorithm adventurers! 🔍✨ Today we’re diving into a slick little indexing challenge from LeetCode — 2200: Find All K-Distant Indices in an Array. At first glance, it seems simple, but crafting an efficient solution requires a clever greedy strategy using pointers. Let’s break it down and uncover the logic behind this clean and optimal approach. 💡 You're given: An integer array nums An integer key An integer k An index i is called k-distant if there's at least one index j such that: |i - j| <= k and nums[j] == key Your task is to return all such indices in increasing order. The goal is to find all indices i such that within a window of distance k from i, there's at least one index j where nums[j] == key. Instead of checking every index i against all j, we can d…  ( 5 min )

For the past few years, I've been diving deep into embedded systems, especially in the context of industrial applications. My journey began with Raspberry Pi, but over time I transitioned to more powerful platforms like Rockchip PX30 and RK3566. These chips offer robust support for Android/Linux, and I’ve found them ideal for building custom HMI panels and smart controllers. In future posts, I’ll be sharing some of the technical challenges, lessons, and optimizations I’ve learned—especially when working with Buildroot, Yocto, and industrial-grade TFT LCD displays. Stay tuned if you're into embedded systems, custom SoCs, or display integration!  ( 3 min )

Atualmente muitos sistemas comerciais fazem uso de funcionalidades e recursos de forma repetitiva, até mesmo com alguns recursos que passam a se tornar procedimentos rotineiros e comuns. A Cron é uma ferramenta presente em vários sistemas e permite realizar o agendamento de tarefas (cronjob) e execução de scripts de forma automática. A mesma pode ser utilizada para processamento de informações em lote, pois também pode ser executada de forma assíncrona. Presente até mesmo em sistemas operacionais Unix, o formato "cron" serve para descrever o intervalo em que determinada cronjob deve ser executada podendo ser descrito conforme imagem abaixo O registro de tarefas é feito através da Crontab, um deamon do sistema operacional que possibilita a criação e agendamento de tarefas. Tarefas agendadas serão executadas a menos que ocorra algum imprevisto, como por exemplo uma outra tarefa estava em execução naquele momento, sendo então necessário que a tarefa não executada seja reconfigurada na Cron a fim de executar a tarefa em outro momento.  ( 3 min )

The promise of quantum machine learning (QML) lies in its potential to revolutionize how we process data and solve complex problems, offering computational advantages far beyond the reach of classical computers. However, realizing this potential in the current technological landscape is complicated by the inherent limitations of today's quantum hardware, a period often referred to as the Noisy Intermediate-Scale Quantum (NISQ) era. Navigating this noise is paramount for developing robust QML applications. The term NISQ, coined by physicist John Preskill, describes quantum computers that have a limited number of qubits (typically 50-100) and are not yet robust enough to perform extensive error correction. These devices are characterized by several key limitations: Limited Qubit Count: The…  ( 8 min )

txtai is an all-in-one AI framework for semantic search, LLM orchestration and language model workflows. Large Language Models (LLMs) have captured the public's attention with their impressive capabilities. The Generative AI era has reached a fever pitch with some predicting the coming rise of superintelligence. LLMs are far from perfect though and we're still a ways away from true AI. One big challenge is with hallucinations. Hallucinations is the term for when an LLM generates output that is factually incorrect. The alarming part of this is that on a cursory glance, it actually sounds like factual content. The default behavior of LLMs is to produce plausible answers even when no plausible answer exists. LLMs are not great at saying I don't know. Retrieval Augmented Generation (RAG) helps…  ( 11 min )

Welcome, fellow developers and curious minds! Have you ever wondered why some code feels like a detailed instruction manual, while other code feels more like a concise wish list? That's the core difference between imperative and declarative programming paradigms. In this article, we're diving deep into the world of declarative programming, exploring its power, elegance, and how it shapes some of the most fundamental tools we use daily, like SQL, HTML, CSS, and even the fascinating logic of Prolog. At its heart, declarative programming is about "what to do," not "how to do it."

You declare your desired outcome, and the sy…  ( 7 min )

大規模なスタイルセットを記述する場合、CSS では限界があります。そこで登場するのが、CSS プリプロセッサ と呼ばれるツールです。その中でも代表的なのが SCSS (サス、Sassy CSS) です。 SCSS は CSS をより効率的かつ構造的に書くための拡張言語です。SCSS コードは、CSS に変換可能であり、実行時には CSS としてブラウザに解釈されます。 メリット SCSS 記法 メリット 変数 $primary-color: #007bff; 一括変更、管理のしやすさ ネスト .parent { .child { ... } } コードの可読性、構造の把握が容易 ミックスイン @mixin my-btn { ... } スタイルの再利用、記述量の削減 インポート @import 'variables'; ファイル分割、管理のしやすさ 変数: 色やフォントサイズなど、繰り返し使う値を定義して管理できます。変更があった際に一箇所修正するだけで済むため、メンテナンスが容易です。 ネスト: CSS セレクタを入れ子 (ネスト) にして書くことができ、HTML の構造を反映した、より読みやすいコードにできます。 ミックスイン: 繰り返し使う CSS のまとまりを関数のように定義し、必要な場所で呼び出して使えます。ベンダープレフィックスの管理などにも役立ちます。 インポート: CSS ファイルを分割して管理し、必要な場所でまとめて読み込むことができます。 $primary-color: #007bff; $font-size-base: 16px; .header { background-color: #f8f9fa; padding: 20px; h1 { color: $primary-color; // 変数を使った計算も可能 font-size: $font-size-base * 1.5; } nav { ul { list-style: none; padding: 0; li { display: inline-block; margin-right: 15px; a { color: #333; text-decoration: none; // & で親セレクタを参照 &:hover { // 色を暗くする関数 color: darken($primary-color, 10%); } } } } } } @mixin button-style($bg-color, $text-color: white) { background-color: $bg-color; color: $text-color; padding: 10px 20px; border: none; border-radius: 5px; cursor: pointer; } .primary-button { // ミックスインを呼び出す @include button-style($primary-color); } .secondary-button { @include button-style(#6c757d); } Vue プロジェクトで SCSS を使うには、SCSS をコンパイルするためのローダー (sass 等) をインストールする必要があります。 npm install -D sass そして Vue コンポーネントの タグに lang="scss" を追加します。 // ここに SCSS を記述 .my-component { h2 { color: blue; } } SCSS を導入することで、CSS によるスタイル定義を構造的に整理できるようになります。それによって大規模アプリでもスタイリングの管理がしやすくなります。  ( 4 min )

Text Compression for Beginners: Building Huffman Coding from Scratch in Swift Ever wondered how file compression actually works? This weekend, curiosity got the better of me, so I decided to dive deep and implement Huffman coding from scratch. 🌳 How Huffman trees work (with visual examples) 📊 Why Huffman is perfect for text/code compression 🔍 Step-by-step walkthrough of the "Mississippi" example ⚡ How to achieve ~50% compression on typical text files Unlike Run Length Encoding (great for images), Huffman coding shines with the kind of files we work with daily - source code, JSON, XML, plain text. It assigns shorter bit sequences to frequent characters and longer ones to rare characters. The best part? It's lossless - your original file is perfectly restored after decompression. A complete compression/decompression system including: Frequency analysis Huffman tree construction Bit-level file operations Compact tree serialization Ready to see how "Mississippi" becomes just 3 bytes?

DevOps — это не отдельная роль, а скорее философия или набор практик, принятых внутри компании/команды. За свой опыт я успел побывать, наверное, во всех вариантах «DevOps»: и как отдельный инженер, жёстко привязанный к команде разработки, и как инженер, Прежде чем поговорить о том, как проводить культурные изменения и нести в команду практики, призванные размыть границы между DevOps и разработкой, Это структура, к которой применимо описание «сисадмины на стероидах». Отдельная организационная единица, «Опять этой разработке что-то надо». «А давайте отполируем вот это решение, хоть оно и не несёт business value». «Давайте переизобретём свой костыль!» (чистейший NIH-синдром — Not Invented Here).

Learn how the Model Context Protocol (MCP) can power smarter, scalable, and stateless AI agent systems. If you’ve ever built anything slightly more complex than a simple chat interface with an LLM, you’ve probably run into the same wall most of us hit: Agents forget things. Context doesn’t persist. Coordination feels clunky. Everything breaks when scale enters. Welcome to the context crisis. The era of building LLM-powered tools and agents is here — but our infrastructure isn’t ready. Most devs are duct-taping memory, state, and agent logic into isolated silos, and calling it a day. But you know that won’t scale. What if you could separate the logic of what a system should do from what it knows and how it remembers? That’s where the Model Context Protocol (MCP) comes in — and no, this is…  ( 6 min )

Author: Tobie Morgan Hitchcock This blog post was inspired by Kolawole Samuel Adebayo's Forbes article on The AI Race Is Now About Databases — Not Just Big Models. The article is insightful to highlight that AI’s bottleneck is no longer compute, it’s about databases: data, storage, and memory. The last few weeks made that shift visible in capital letters, with multiple database acquisitions in the AI space. These aren’t just tech M&A headlines. They’re a collective admission: to scale AI, you first have to rethink how memory (not only data) is managed. The frontier has moved down-stack. It’s no longer just about building bigger models or fine-tuning LLMs. It’s about how agents access, reason over, and persist context in real time. In our conversations with enterprises, we’ve noticed that m…  ( 4 min )

Ever needed a centralized configuration manager in your JavaScript app? 🤔 In modern JavaScript apps, managing shared state or configuration often means reaching for heavy tools like Redux, Zustand, or context APIs. But what if you're working on a small utility, a framework-agnostic widget, or just need a simple global config? This is where the Singleton pattern with an IIFE (Immediately Invoked Function Expression) comes in handy. It offers a lightweight, zero-dependency way to encapsulate state, avoid global pollution, and keep things clean—all without introducing a full-blown state manager. const configManager = (() => { let config = {}; return { set(key, value) { config[key] = value; }, get(key) { return key ? config[key] : config; } }; })();…  ( 3 min )

Input Embedding Space Gradients This is the first in a series of posts on the question: "Can we extract meaningful information or interesting behavior from gradients on 'input embedding space'?" I'm defining 'input embedding space' as the token embeddings prior to positional encoding. The basic procedure for obtaining input space gradients is as follows: Transform tokens into input embeddings (but do not apply positional embedding). Run an ordinary forward pass on the input embeddings to obtain a predicted token distribution. Measure cross-entropy of the predicted distribution with a target token distribution. Use autograd to calculate gradients on the input embeddings with respect to cross entropy. The result is a tensor of the same shape as the input embeddings that points in the dire…  ( 7 min )

When working with geographic data in Python, calculating the distance between two points on Earth is a common task. But not all methods are created equal! Here’s a quick guide to the most popular approaches and why geopy.geodesic is often the best choice — especially if you're working on Django, GIS, or logistics platforms. Some libraries (or naive code) use the Pythagorean theorem to compute distance between lat/lng pairs: # ❌ Not recommended for geographic coordinates! from math import sqrt def euclidean_distance(coord1, coord2): return sqrt((coord1[0] - coord2[0])**2 + (coord1[1] - coord2[1])**2) The Earth is not flat. This method ignores the planet’s curvature, so it becomes wildly inaccurate as distances grow. These formulas treat the Earth as a perfect sphere: # ✅ Haversine e…  ( 4 min )

For decades, the narrative has been the same, the Big Tech, with its colossal R&D budgets, server farms, and armies of PhDs, sets the standard for customer experience. Their AI-powered recommendation engines, impossibly fast support bots, and hyper-personalized journeys have felt like an unachievable competitive goals. For most startup founders, small business owners, and product leaders, the game seemed rigged honsetly. but guess what That era is over. There are Three fundamental shifts have demolished the old barriers to entry whuich i called the great equalizer The API-fication of Intelligence: Foundation models like OpenAI's GPT-4, Anthropic's Claude, and Google's Gemini are now utilities. You can "rent" a world-class AI brain via a simple API call for pennies. Big Tech did the heavy lifting of training; you get to do the creative work of applying it. The Rise of the No-Code/Low-Code "Nervous System": You don't need a team of machine learning engineers to connect these AI brains to your business processes. Platforms like Zapier, Make.com, and Retool act as a central nervous system, allowing you to build sophisticated workflows that link your CRM, support desk, and marketing tools with powerful AI capabilities—often with zero code. The Agility Advantage: A small team's greatest superpower is its proximity to the customer and its lack of bureaucracy. While a Big Tech company debates a new feature in committee for six months, you can identify a customer pain point on Monday, build a prototype AI solution on Wednesday, and deploy it by Friday. The game has changed. The resources are in your hands, the cost of entry has collapsed, and the agility of a small team has never been more valuable. The question is no longer if you can compete with Big Tech on AI-powered customer experience. The question is, how will you choose to win?  ( 4 min )

Rust is known for being safe and fast but to get there, you need to understand some core concepts. Let’s break down lifetimes, traits, enums, and pattern matching with clear examples. Rust makes sure you don’t use data that’s already gone. Lifetimes are how Rust tracks how long references are valid. fn longest(x: &'a str, y: &'a str) -> &'a str { if x.len() > y.len() { x } else { y } } This function returns the longer of two string slices. The tells Rust: "The result reference will live as long as both x and y." ✅ Without this, Rust won’t know how long the returned reference lives and could reject your code to keep things safe. Traits define what methods a type must implement. Think of them like "skills" a type can have. trait Speak { fn speak(&self); } struct Dog; …  ( 4 min )

I didn’t set out to make a reading list. Honestly, most of the books I’ve found useful were ones I stumbled on. A friend mentioned it, or I saw it in a strange corner of a bookstore, or I picked it up, put it down, then picked it back up two years later when something in my life finally made me ready for it. What’s strange is, a lot of them weren’t directly related to work. Not in the obvious way. They weren’t books about “career growth” or “leadership hacks.” But they shifted something in me—how I make sense of chaos, how I ask questions, how I interpret what’s not being said in a room. So no, this isn’t a ranked list. I’m not trying to be helpful or definitive. I’m just trying to trace a line backward—through the ideas, arguments, phrases, and small turning points that stuck.

Blazor Server makes it easy to build web apps with intuitive syntax, but handling dates and times (DateTime) requires special attention. Can you spot the bug in the following code? @DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") The answer: This displays the current time on the server, not the user's local time. The time is formatted according to the Blazor host server's time zone, which may not match the user's time zone. This bug occurs when the Blazor host server's time zone ≠ user's time zone. It's a subtle issue that's easy to miss during development. A similar problem arises with date/time input fields. You can't tell which time zone the entered value refers to. @code { private DateTime dt { get; set; } p…  ( 5 min )

DX-First Thinking: Why I Added @EnableTenantIsolation to My Spring Boot Starter Day 3 of building multi-tenant-springboot-starter was less about code, more about mindset. I wanted developers to switch between DATABASE, SCHEMA, and SHARED isolation strategies for tenants. The default Spring Boot way would be application.yml: tenant: strategy: DATABASE That works, but I asked myself: “What would it look like if Spring had built this?” So I created: @EnableTenantIsolation(strategy = TenantIsolationStrategy.SCHEMA) 💡 This annotation uses ImportBeanDefinitionRegistrar and EnvironmentAware to inject the tenant.strategy key into the Spring Environment — before anything binds. What I learned: @import(...)

Mastering Data Compaction in Apache Iceberg: A Production Deep Dive Introduction The relentless growth of data in modern applications presents a significant engineering challenge: maintaining query performance on ever-increasing datasets. We recently faced this at scale while building a real-time analytics platform for a large e-commerce company. Ingesting clickstream data at 100K events/second, coupled with historical order data totaling over 500TB, resulted in query latencies exceeding acceptable thresholds for dashboarding and reporting. The root cause wasn’t compute or storage capacity, but the proliferation of small files and inefficient data layout within our data lake. This led us to deeply investigate and optimize data compaction strategies within Apache Iceberg, a …  ( 7 min )

I used to be an Nginx fan. Had it running everywhere - personal projects, client sites, production servers. The config files made sense once you learned them, and it was rock solid.

VoiceReach is a voice message broadcasting tool that lets users send a single typed message to multiple recipients via automated phone calls. The app uses a Text-to-Speech (TTS) API to convert the message into a realistic voice and then places calls using Twilio to deliver the audio. Designed for quick announcements, invitations, or alerts, VoiceReach eliminates the need for repetitive manual calls, making communication faster and more efficient. Built with Node.js, Express, and a simple HTML/CSS frontend, it's a powerful yet user-friendly solution for voice-based outreach. GitHub repo - https://github.com/madhavdandona123/murf-ai VoiceReach has powerful real-world applications for anyone needing to deliver voice messages to multiple people quickly and reliably. Community leaders, school administrators, event organizers, political campaigners, and small businesses can use it to send announcements, alerts, or invitations without making manual calls. It’s especially useful for reaching people who may not regularly check texts or emails—such as elderly recipients or rural communities. Compared to traditional methods like group calls or bulk SMS, VoiceReach improves efficiency by automating the process with natural-sounding voice and delivering it through a personal phone call, which feels more direct and urgent. It reduces human effort, saves time, and increases the likelihood that important messages are heard.  ( 3 min )

Adding alias in your Gitbash terminal can help you speed up your workflow when using the terminal. ⚡️ In this tutorial, I am going to guide you how you can configure the aliases for your day-to-day commands. 🚀 First of all open the Gitbash and type following command in it. alias And you will see an output something like below image. It will give the list of aliases which are configured. 📋 If you see nothing, then no aliases are set. So don't worry. 😅 To set the alias for any command type following in the terminal. ✨ alias new_command_name='old_command_name' The alias set within the image will create an alias for git commit. Now I can just type gc -m and it will commit my code. 🎯 And that's it, you have configured your first alias. Hurray!!! 🎊 Hold on, it's not over yet. ⚠️ If you just close the terminal and try to re-run that alias again, it will throw error like this. 😱 What?! You will think I just set it and now it's gone. Yup it's gone. 💔 Because aliases set with alias are session based means they are deleted once the terminal is closed off. So how can we make it permanent??? 🤔 Well, there is a way make it permanent. 💡 It's .bash_profile file, it's location differ from OS to OS. For windows it would be OS_Drive/Users/ and for ubuntu it's present in root and you can run ls -la to see it. 📁 Open the .bash_profile file and edit it. ✏️ Congratulations.

Then you realized they wanted something their boss could actually look at without squinting at raw data tables. Here's the thing nobody tells new DBAs: Writing great queries is only half the job. The other half is making that data speak to people who don't think in SELECT statements. That's where SSRS comes in. And no, it's not as scary as it sounds. SSRS (SQL Server Reporting Services) is Microsoft's tool for turning your SQL query results into professional, interactive reports. Think of it as a translator between your database and everyone else. You know that query you wrote to check which products are selling …  ( 5 min )

Tired of checking Amazon every day to see if a product’s price went down? So was I. That’s why I built a simple tool that automatically tracks prices on multiple Amazon items and alerts me when they drop — no browser extensions, no manual checking. In this post, I’ll walk you through: The problem that led me to build this How it works behind the scenes Key features Lessons I learned And how you can get or build something similar I often add items to my Amazon wishlist and wait for discounts. But unless I checked manually — daily or weekly — I’d miss the best deals. Most price-tracking extensions are: Browser-dependent Limited to one product Bloated or subscription-based As a developer who loves automating boring stuff, I knew I could do better.

Hey folks. So what now, fellow developers? Panic, or polish your résumé and lean in? Inside this whirlwind sits both risk and an outsize slice of opportunity that might not show up again in our lifetimes. Let me live-code the explanation for a second. Forget the power-point speak; think of AI as the capability to feed an algorithm mountains of observations and then let it tweak its own playbook as fresh examples roll in. The decision logic emerges from the pattern, not from a human’s final check-mark. Artificial intelligence acquires proficiency in much the same way a specialist absorbs lessons from practice. An influx of fresh information typically translates into perceptible improvement. Professors and practitioners usually separate three principal disciplines within the field. Machin…  ( 6 min )

Hi, It’s been a while since I posted anything tech-related. So, my friends, here we have it. This article is all about how and why I used MindsDB for my next project: KbNet. Before I go deep into the technical rabbit hole, let me quickly tell you what MindsDB is. MindsDB is this cool open-source project that makes building AI-driven applications super smooth. It basically reduces the headache of connecting a bunch of data sources and managing AI integrations in your app. So instead of writing custom adapters and creating extra packages for every new data source, MindsDB just says: "Relax, bro, I got you." Connect multiple data sources and pipe them into a unified output. Create pre-built AI models with prompt templates (supports OpenAI, Google Gemini, and more). Run background jobs and…  ( 6 min )

Introduction Machine learning is no longer an experimental discipline—it's a cornerstone of critical infrastructure in industries ranging from finance to healthcare. As a result, model archiving has become a non-negotiable aspect of operational machine learning. In this blog, we explore what ML model archiving is, why it matters, and how Jozu and KitOps ModelKits provide the most robust, scalable, and future-proof ML Model Archiving Tool available today. ML model archiving is the process of storing machine learning models—along with their metadata, dependencies, training data references, and environment settings—in a secure and retrievable format. Model archiving is critical for several reasons: Auditability & Compliance: Regulations like GDPR, HIPAA, and the EU AI Act increasingly requi…  ( 5 min )

Countless applications. Hundreds of rejection emails. Failed interviews. It was easily one of the worst experiences of my career. Let me tell you how I eventually found my current job. It was May 2023. I saw a new meeting pop up on my calendar with no description, just an invite. Instantly, I knew what it was about. Companies were laying off developers left and right. I had already heard rumors about cuts at my company too. When I joined the call, I saw my HR representative. She told me that I was being laid off along with the rest of my team. My heart sank. I didn't know what to think or do. I accepted it quietly, packed up my things, and left the company that same day. It was a weird feeling, I'd never been laid off before. I'd always left companies on my own terms. This was completely d…  ( 5 min )

Think of it as a family tree for your data. fn main() { // COMPLETE PROGRAM: Demonstrating scope trees and lifetime relationships println!("=== Scope Tree Visualization ==="); scope_tree_example(); println!("\n=== Lifetime Elision Rules ==="); elision_examples(); println!("\n=== When Elision Fails ==="); explicit_lifetime_examples(); println!("\n=== Multiple Lifetime Parameters ==="); …  ( 13 min )

Today! We’re going to learn TypeScript like you’re a smart 5-year-old who loves to build things and asks “why?” (which is the best thing ever). & yes “why?” is my way of learning. I've divided this into 20 Chapters. and will go one by one and each will be of 2 - 3 min. of read. This is Chapter ⓵ TS Mastering 🤔 Imagine this: You’re building a toy robot (Yes, we are learning it like 5) . In JavaScript, you just glue parts together however you like even if you accidentally attach a banana instead of a motor… the robot won’t complain until it breaks later! 🍌🤖💥 But with TypeScript, it’s like having a smart helper who says: “Hey! That’s not a motor... that’s a banana. Are you sure you want to do that?” That helper saves you from mistakes before you even turn on the robot. Cool, right? TypeScript = JavaScript + Superpowers (called Types) write safer, smarter code. TypeScript helps you catch errors early It makes your code easier to understand It works great with modern tools and editors 💬 Let’s look at a simple example: // JavaScript function add(x, y) { return x + y; } add(5, "10"); // 🙃 oops! This gives "510" instead of 15! Now in TypeScript: function add(x: number, y: number): number { return x + y; } add(5, "10"); // ❌ ERROR! You gave me a string, I wanted a number! TypeScript tells you before you even run it that something’s wrong. Yes‼️ TypeScript is just JavaScript with extra safety. type annotations. 🐞 Catch bugs before they happen 👯‍♂️ Work better in teams 💻 Get amazing auto-suggestions in your code editor If you enjoyed this and want to master TypeScript and other technologies, follow the series and drop a like!🤝 I’m a passionate software developer sharing the cool things I discover, hoping they help you level up on your coding journey.

Day One was me reacquainting myself with Figma. I started by reviewing the basics of the interface and exploring the various tools and features available. I also took some time to familiarize myself with the keyboard shortcuts and the different ways to navigate the canvas. Juxtopposed video on this was super helpful and is what kicked off this idea! Who doesn't like cards on websites. They come in all sorts of... well not shapes but sizes and designs. I've seen truly beautiful ones and wanted to get better with playing with multiple layers. I knew I wanted a simple card consisting of a header, small paragraph, an icon, and a gradient. I often see cards come in threes and when I'm playing with colors in counts of three it's very difficult for me to not think of Pokémon, so I just went with it! There are actually several layers to each card: A circle with it's midpoint roughly anchored to the card's bottom right corner. A rectangle above it acting as a mask for the circle and bringing in the darker emerald/blue/rose colors. A rectangle of the same size above that with a semi-opaque and lighter emerald/blue/rose color with an inner-shadow of the darker color. The text and icon are the final layers. Even the button has a semi-transparent background which allows the main color to bleed through, as well as a semi-transparent border. These are simple but I like them! There is no goal to do one per day, but I’d like to do at least four three week so I can see progress. I also plan to write a short blog (or micro-blog, if you will) about each design I create or copy. If you’re in a similar boat, I encourage you to jump on board and do the same! I’ll be sharing my progress on X/Twitter and LinkedIn. If you’re interested in following along, feel free to follow me on those platforms!  ( 3 min )

If you are a developer or a system administrator, you might have heard of Docker and Virtual machines. Both are technologies that allow you to run applications in isolated environments, but they have different advantages and disadvantages. In this article post, I will compare Docker containers and virtual machines, explain their use cases and examples, and help you decide which one is better for your needs. A virtual machine (VM) is like a mini-computer that runs inside your main computer. It has its own operating system, memory, disk space, CPU, network interface, etc. You can run any application on a VM as if it was running on a real computer. For example, you can run Windows on a VM inside your Linux computer, or vice versa. Some of the benefits of using VMs are: They provide full isola…  ( 5 min )

DeFi isn’t exactly known for stability. Between hype cycles, market-wide volatility and social-media-triggered moves, most tokens tend to mirror the chaos around them. But every now and then, a token breaks that pattern. In 2025, $WBT coin has shown a different trajectory - not only resisting downturns, but reaching five new all-time highs in less than six months! While most centralised exchange tokens ($BNB, $OKB, $KCS, $GT) have stayed flat or fallen below their historical highs, $WBT has continued climbing. For reference: $BNB hit its ATH of $788.84 in Dec 2023 and hasn't surpassed it since $OKB last peaked in Mar 2024 $KCS hasn’t seen a new ATH since 2021 $GT joined WBT in reaching a new ATH in 2025 🧨 There are several macro signals that align with WBT's recent rise, and prove its growth as infrastructure-backed: trading volume surged alongside each ATH; liquidity pools deepened, especially post-margin launch; holder count steadily increased (on-chain data shows consistent wallet growth). WBT's case challenges a common assumption in crypto: that price action must come from hype & artificial pump. In contrast, it shows that consistent development, deep integration and clear tokenomics can still drive growth - even in noisy market conditions. For a deeper dive into WBT's recent performance, check the full article from CoinMarketCap. If you're building in 2025, WBT is a reminder that steady growth still comes from solving real problems, not just riding trends.  ( 3 min )

CSS とは Web ページの見た目を装飾するのが CSS (Cascading Style Sheets) です。HTML でページの骨格を作り、それに対して CSS で色、フォント、レイアウトなどを指定します。 CSS では、HTML 要素にスタイルを適用するためのルールを記述します。 セレクタ { プロパティ: 値; プロパティ: 値; } 用語 説明 例 セレクタ どの HTML 要素にスタイルを適用するかを指定します。 (下記「セレクタの種類」参照) プロパティ 変更したいスタイルの種類 color, font-size, margin 値 プロパティに設定する具体的な値 blue, 16px, 10px 20px セレクタは以下の 3 種類に大別されます。(疑似要素を含めるともう少し増えます。) これらを使い分けることで、スタイル適用範囲に幅と柔軟性を持たせることができます。 種類 例 要素セレクタ p { color: blue; } (すべての 要素) class セレクタ .my-button { background-color: green; } (タグに　class="my-button" 属性を持つ要素) ID セレクタ #header { font-size: 24px; } (タグに id="header" 属性を持つ要素) h1 { /* 文字色を濃いグレーに */ color: #333; /* フォントサイズを 32 ピクセルに */ font-size: 32px; /* テキストを中央揃えに */ text-align: center; } .button { /* 背景色を青に */ background-color: #007bff; /* 文字色を白に */ color: white; /* 内側の余白 */ padding: 0.2em 0.4em; /* 枠線をなくす */ border: none; /* 角を丸くする */ border-radius: 0.2rem; /* マウスカーソルをポインターに */ cursor: pointer; } .container { /* この要素を Flexbox コンテナにする */ display: flex; /* 子要素の水平方向: 両端に配置 */ justify-content: space-between; /* 子要素の垂直方向: 中央に配置 */ align-items: center; } Vue ではスタイルをどこに書くのでしょうか。 一つの方法は、すでに見た単一ファイルコンポーネント (SFC) すなわち .vue ファイルの中で タグに記述する方法です。そのコンポーネントに特化した CSS を記述できます。 共通のスタイルやユーティリティ class 定義を外部ファイル (.css) に記述することも可能です。希望の場所で読み込んで使用します。  ( 3 min )

I've been a longtime fan of a puzzle website with 40 incredibly well-made intellectual games. Recently, I decided to give it a modern overhaul. I don't have much front-end development experience, so I used Cursor and Claude to assist me throughout the process. I want to share why I decided to refactor this classic collection and how I efficiently accomplished this task with the help of AI, especially tools like Claude. Many years ago, I first encountered Simon Tatham's Portable Puzzle Collection. It's a set of brilliantly conceived and logically rigorous games, all written in C, capable of running on various old devices. I was hooked, completely captivated by their clever design. I even took a look at his C source code, and it's beautifully written. The author also developed PuTTY, which i…  ( 6 min )

Recently, I participated in the Forge Quest Hackathon by Atlassian—and it turned out to be exactly the kick I needed. For a long time, I had let my Postman Doc app on the Atlassian Marketplace go stale. Life happens. Forge evolves.

Our jobs require a certain level of precision, so it’s natural that we’ll want to take an exact approach to our software delivery metrics. Some folks might even like a detailed standard to pin their measurement to so they can be sure it’s exactly right. Investing too much in precision is wasteful and takes time away from something far more important: doing something in response to the data. The DORA metrics are the most popular DevOps metrics. The precision needed for DORA metrics is low, and gets even lower the higher you perform. In general, you want to get a temperature check for the kind of performance you have. For the throughput metrics, the unit of measurement is more informative than the number. It’s more interesting whether you measure throughput in months, weeks, days or hours th…  ( 6 min )

Page speed matters more than ever. Google’s Core Web Vitals framework has made TTFB and FCP crucial for ranking well. After hitting limitations with SSR, we decided to move to SSG + ISR on two of our most active content sites: nolcardbalanceae.com — public transport and NOL card balance check guides wgustudentsportal.com — student tools and academic resources Both platforms initially used getServerSideProps, but with traffic rising and SEO slipping, performance audits with PageSpeed Insights and Lighthouse confirmed what we feared: server response time was hurting the experience. We migrated to getStaticProps with Incremental Static Regeneration (ISR), letting us statically generate thousands of guides and tools for both nolcardbalanceae.com and wgustudentsportal.com. return { The result? Pages served instantly, with fresh data reloading in the background. Vercel’s 45-minute build limit created a blocker during deployment. With so many static pages, we exceeded the threshold regularly. To fix it: We batched content at build time Stored it as local JSON Called that in getStaticProps() This brought total build time below 30 minutes and gave us predictable, fast deployments. After implementation: nolcardbalanceae.com saw bounce rate drop by 20% wgustudentsportal.com pages loaded under 1 second Lighthouse scores consistently hit 95+ Googlebot crawled 3× more URLs per day We followed Next.js best practices and Google’s performance guidelines to the letter — and it paid off.  ( 3 min )

About a year ago, a dev friend of mine landed a job at a well-known product company. He was crushing it: delivering on time, writing solid tests, picking up weekend hotfixes — even showing up to standups with a fever. Then came the performance review. His manager told him: you’re not Senior yet. You lack confidence and initiative.” It hit hard. Especially after months of 60+ hour weeks and constant firefighting. A month later, he quit. He joined another company. Senior Software Engineer title. Now here’s the question: 💬 Who was right — the first company that didn’t see a senior, or the second that saw one immediately?

Let’s get something straight: your code is not a majestic redwood. It’s a houseplant. A needy, fickle little thing that demands regular sunlight, occasional pruning, and a watchful eye—lest it curl up, die, and stink up the whole damn repo.

Generative AI has exploded into the mainstream, with Large Language Models (LLMs) like GPT-4 leading the charge. But as impressive as these models are, integrating them into real-world applications requires more than just an API call. That’s where LangChain comes in. In this post, I’ll walk you through how LLMs and Generative AI work together — and why LangChain is becoming the go-to framework for building intelligent, context-aware AI applications. At its core, an LLM is a machine learning model trained on vast amounts of text to understand and generate human-like language.

For centuries, the image of education has remained stubbornly consistent: a teacher imparting knowledge to a room of students. But beneath the surface, a quiet revolution is underway. Artificial intelligence is no longer a futuristic fantasy; it’s actively reshaping how we learn, how we teach, and even what we learn. This isn't simply about digitizing textbooks or automating grading—it’s a fundamental shift in the architecture of education, a move toward systems that adapt, personalize, and anticipate the needs of every student. But the promise of AI in education isn’t without peril. As algorithms permeate the classroom, critical questions around equity, privacy, and the very nature of human learning demand urgent attention.

Serving static files—like CSS, JavaScript, images, or fonts—is a basic requirement for any web application. Even in a minimal Python framework, you can add support for static file delivery with only a few lines of code. Static assets are essential for rendering pages and enhancing UX. Without them, even the most functional web app will look and feel incomplete. You may use a reverse proxy (like Nginx) in production, but during development or for embedded apps, your framework should handle static file serving directly.

Launching a WordPress site in 2025 isn’t just about spinning up a theme and hitting “publish.” With users expecting faster performance, mobile responsiveness, and secure UX out of the gate — your launch process has to be strategic. I’ve launched sites for clients and personal projects, and I noticed a recurring pattern: the same pre-launch mistakes cause headaches later. So I started using a structured checklist — and it’s made all the difference. Here’s a breakdown of what I now do before going live with any WordPress site. Choose a reliable host (SSL, backups, fast support) Register a clean, brandable domain Ensure server location suits your target audience (e.g., US-based server for US traffic) Yoast SEO or Rank Math (SEO) UpdraftPlus (backups) Wordfence or Sucuri (security) Elementor or block-based editor for layout Use a responsive, lightweight theme Customize branding elements (colors, fonts, CTAs) Test across breakpoints (mobile/tablet/desktop) Enforce strong passwords & 2FA for admin users Update all plugins/themes before launch Install firewall + login protection plugin Meta titles + descriptions XML sitemap submission Keyword-optimized content + internal linking Compressed images + alt tags Google’s Mobile-Friendly Test ✅ Optimize for Core Web Vitals (LCP, FID, CLS) Check tap targets, menu responsiveness No broken links or 404s Contact forms working Speed test (PageSpeed, GTmetrix) Full backup before going live I’ve put together a detailed checklist that includes exact tools, plugins, and tips I use with clients.

I remember the first time I struggled to add the same extra behavior to many functions. I had a logging requirement on every class method, so I tried subclassing or adding if checks everywhere. My code became a tangled web of inheritance and flags. Then a colleague showed me decorators – and my mind was blown. A decorator is like giving your function a special coat: you wrap extra behavior around it without changing its core logic. As one tutorial puts it, decorators “allow you to wrap another function—to add or modify its behavior—without changing the original function’s code”. It felt as elegant as putting a gift in a beautifully decorated box. enhances it.

The introduction of React 19, Server Components, Server Actions, and other developments such as the React Compiler (Forget) are leading the ecosystem towards a more declarative, reactive and server-focused paradigm. We will deconstruct in this blog: Why useEffect can be more troublesome than helpful? What the modern React provides as alternatives that are cleaner? Practical cases in which useEffect can now be eliminated When is useEffect necessary? (Img Source) What Replaces use…  ( 5 min )

We've all been there. You're building an awesome app, everything's going smoothly, and then you hit that requirement: "Oh, and we need to send welcome emails, password resets, order confirmations, and notifications." Suddenly, your simple project turns into an email engineering nightmare. 📧💀 The Email Development Black Hole // What it actually becomes: // 200+ lines of email configuration later... According to recent surveys, developers spend an average of 40+ hours just building and maintaining email systems. That's a full work week that could be spent on your core product features! The Hidden Complexity of "Simple" Emails Template Management: HTML emails that work across all clients Each of these could be a project in itself. javascript// Traditional approach - hours of work // AI-powered approach - one line ✅ Professional email design Real-World Example: Password Reset ; // After: Natural language Send a secure password reset email with a button linking to ${resetUrl}. }); The AI generates a professional, secure-looking email with proper styling, clear call-to-action buttons, and even includes security messaging automatically. From Template Hell to Natural Language No more managing multiple template files From Hours to Minutes Prototype emails instantly From Maintenance Burden to Set-and-Forget AI handles design consistency Getting Started Identify your email types: List all the emails your app needs to send The key is starting with simple transactional emails (welcome, reset, confirmation) and expanding from there. What's Your Experience? P.S. If you want to experiment with AI email generation, I've been testing it with contacted.io - they have a free tier that's perfect for trying out this approach. The interactive playground lets you test prompts before implementing.  ( 5 min )

** What Are Chrome Net Internals?** Chrome's Net Internals is a collection of diagnostic tools provided by the browser. It enables users to examine and control network-related information, such as DNS cache, sockets, proxy settings, etc. To launch: Enter chrome://net-internals/#dns in the Chrome address bar and hit Enter. Chrome, over time, caches DNS records to make websites load faster. Stale or damaged DNS records, however, may cause the following errors: DNS_PROBE_FINISHED_NXDOMAIN ERR_NAME_NOT_RESOLVED Weblinks failing to load Flush the DNS cache deletes these cached records so that Chrome can retrieve new DNS information from the network.

🔹 Problem: 2081 K Mirror Numbers Difficulty: Hard Tags: #Palindrome, #BaseConversion, #Math, #BruteForce Given two integers k and n, you are to find the sum of the first n positive integers that are palindromes in both base 10 and base k. k-mirror if: It's a palindrome in base 10 (normal decimal), and It's a palindrome in base k. Brute Force Idea: Check every number starting from 1, See if it's a palindrome in both base 10 and base k. Keep going until I find n such numbers. This idea is simple, but extremely slow and will TLE for large n. What I Figured Out: I realized that we should generate palindromes only in base 10 and check if they’re also palindromes in base k. This eliminates checking non-palindromic candidates, which saves a lot of time. I also figured that we can build palindr…  ( 4 min )

While speculative, this analysis uses historical precedents, present vulnerabilities, and global interdependence to paint a realistic picture of a world economy torn by war. Collapse of Global Trade Networks WWIII would almost certainly paralyze international trade. Maritime routes would be militarized or blocked, airspace restricted, and shipping infrastructure targeted. The World Trade Organization (WTO) and other global frameworks would falter. Container shipping, which accounts for over 80% of global trade by volume, could grind to a halt. Supply chains, particularly those linked to semiconduc…  ( 5 min )

I'm subscribed to Adam Johnson's blog and usually really enjoy his writing - it's practical, deep, and no-bullshit. But one recent post, Python: sharing common tests in unittest, caught me off guard. It describes a "neat" pattern: write reusable test logic in a base class, subclass it to test multiple objects, hiding the base class from unittest discovery. While the intent is fine - DRYing out duplicated test code - the result is fragile, confusing, and just not worth it. Here's why. # Sample units to test class Armadillo: def speak(self) -> str: return "Hrrr!" class Okapi: def speak(self) -> str: return "Gronk!" # Test module class BaseAnimalTests(TestCase): animal_class: type def test_speak(self): sound = self.animal_class().speak() self…  ( 4 min )

👋 Introduction: Ever lost an important ChatGPT conversation due to a refresh or message limit? I did — way too many times. That’s why I built ChatBridge, a lightweight Chrome extension that lets you save and resume your ChatGPT chats any time. No servers. No logins. Just simple, offline chat memory. 💡 The Problem: ChatGPT is powerful, but one frustrating limitation is the lack of persistent memory in the free version. Once you refresh the page or hit your message limit — poof 💨, your chat is gone. If you’re using it for research, writing, or learning, it’s a huge productivity loss. 🛠️ The Solution — ChatBridge ChatBridge gives users the ability to: Paste a chat into the popup Title it for easy recall Save it to local storage Reopen anytime — even offline It’s a simple way to give ChatGPT a “manual memory.” ⚙️ How I Built It: Stack: HTML5 / CSS3 JavaScript (ES6+) Chrome Extension APIs localStorage for persistence The extension runs entirely in your browser. Nothing leaves your device. I used manifest v3 and added a user-friendly popup UI with auto-updated saved chat history. Handling edge cases like refreshes and repeated saves Designing a minimal yet functional UI 📦 Try It Out: 👉 GitHub Repository - https://github.com/pratibha131/chatbridge-extension It’s open-source and easy to install via chrome://extensions → "Load Unpacked". 🙌 What’s Next?

The Memory Wall Problem Most vector indexes prioritize RAM for low latency. HNSW, for example, achieves 95% recall at <5ms for 100M vectors but requires ~500GB RAM. At 1B vectors, RAM costs exceed $10k/month on cloud instances—prohibitively expensive for many teams. DiskANN flips this model: Core Innovation: Stores graph structure and full vectors on SSDs Memory Footprint: Requires 15–50× less RAM than HNSW Tradeoff: Accepts ~10–20ms latency (NVMe SSDs) for billion-scale searches In my 1B vector test (768-dim), DiskANN used 32GB RAM versus HNSW’s 512GB while maintaining 95%+ recall.

Structured Text Computing Requirements Structured text files are a common data storage method, such as this score.txt file, which records the scores of students in all classes. The first row is the column name, and each subsequent row is the data of a student, separated by tab within each row.

Writing Java code is also very tedious, but using SPL is very simple. First, let's see how to load the file.

Routing is the core mechanism that connects HTTP requests to the appropriate code handlers. In a lightweight Python web framework, implementing efficient and flexible routing allows you to build clean URLs, handle dynamic parameters, and organize your app logically. When a client sends a request, the framework must decide which function or method will process it. Routing takes the request path and HTTP method, then matches it against predefined patterns to find the correct handler. The simplest routing matches fixed paths: /home → serves home page /about → serves about page You can store routes in a dictionary keyed by path: routes = { "/": home_handler, "/about": about_handler, } Lookup is then a quick dictionary access. Real apps need dynamic routes like /users/42 where 42 is …  ( 4 min )

It’s an architectural pattern that separates the responsibilities of: Commands: actions that change state (e.g., create, update, delete) Queries: actions that read data (e.g., get list of tasks, fetch user info) This separation contrasts with traditional CRUD, where reads and writes are typically handled by the same service or con…  ( 4 min )

This guide will walk you through adjusting the session timeout duration in your Laravel application. You’ll explore two straightforward techniques: Editing the .env file Editing the config/session.php configuration file Both approaches are compatible with all major Laravel versions — from Laravel 5 up to Laravel 12. A Laravel session is a way for your web application to remember information about a user across multiple page visits. Think of it like this: When someone visits your website and logs in, the session acts like a temporary memory that stores key details — like their user ID or login status — so they don’t have to log in again every time they visit a new page. Laravel handles this automatically behind the scenes. It gives each visitor a ** unique session** ID (usually stored in a browser cookie), and stores the data either in files, a database, or another storage system — depending on how your app is set up. Open your .env file , by default SESSION_LIFETIME *is **120 minutes *, which means user sessions will expire after **2 hours of inactivity. Modify the SESSION_LIFETIME value in your .env file: SESSION_LIFETIME=525600 # 1 year (60 minutes × 24 hours × 365 days) For a shorter session, like 30 minutes: SESSION_LIFETIME=30 Laravel will automatically use this value to control how long a session remains active. open, the session.php ,Alternatively, you can define the session lifetime directly in the config/session.php file: 525600 , # 1 * 60 * 24 * 365 ..................................................... ]; If you've updated the session lifetime in config/session.php but it's not reflecting in your application, make sure to: 👉 Want the full code and detailed explanation?

What’s the cost of a single bug slipping into your FinTech app’s production environment? For some teams, it’s a minor support ticket. For others, it’s an emergency rollback, an audit failure, or worse – a social media storm followed by thousands of users deleting the app. Now multiply that risk by the velocity of your releases. The average FinTech platform deploys multiple times per week. Each release introduces new features, touches old logic, and reawakens forgotten bugs. Every push is a potential trigger. The numbers aren’t comforting. According to Statista, 6 out of 10 users will abandon a banking app due to performance issues. Not poor UX. Not pricing. Performance.

Just before the election, a secret plan was revealed: all fruits secretly agreed to vote for the same fruit! Honestly, we get it - fruits are clearly tired of the long-running vegetable monarchy. More and more vegetables are being added to smoothies, carrot cakes are gaining popularity... that would drive anyone bananas. We don’t know which fruit they’ve chosen as their…  ( 5 min )

Ever launched a product and thought: "If I just add one more killer feature, users will finally get it." But they don’t. They bounce. They churn. They never even activate. 🚨 The problem isn’t the features. It’s that users never learned how to use them. Let’s talk about the silent killer of SaaS products: poor onboarding. More features often overwhelm users. Especially in tools for devs, designers, or clients—throwing too much too soon means they’re lost before they start. 🧠 Users don’t need everything, they need clarity. Great onboarding helps users: Understand the value proposition instantly Experience a quick win (aka Aha! moment) Stick around and explore more Let’s break down how to create onboarding that converts: Static tutorials or docs can feel like reading a dictionary. Instead,…  ( 4 min )

As applications become more sophisticated and users demand faster, smoother experiences, ensuring high performance is no longer optional. Real User Monitoring (RUM) has become a vital tool for developers, DevOps teams, and site reliability engineers to understand how their applications perform in real-world conditions. Real User Monitoring (RUM) is a technique that captures how actual users interact with your website or application in real-time, across diverse geographies, devices, and network conditions. It relies on lightweight scripts embedded in the frontend to monitor key user events like page loads, API calls, JavaScript errors, and navigation paths. Rather than simulating traffic, Real User Monitoring (RUM) captures data from real sessions, offering visibility into: Load times by re…  ( 6 min )

Git rebasing can sometimes feel like deciphering a cryptic incantation—especially when your IDE throws around the term “onto” without clear context. Whether you’re working with the intuitive interface of IntelliJ or the plain commands on the terminal, understanding what “onto” means is essential. At its core, the rule is simple: The branch on the left-hand side (LHS) is the one that gets rewritten, while the branch on the right-hand side (RHS) remains safe. In practice: Always have your stable branch (usually main) on the RHS. In this post, we’ll first break down how IntelliJ presents this concept and then show that the same logic applies on the Git CLI. When working with IntelliJ, you’ll often see rebase options that explicitly mention both branches. Typical examples are: Rebase feature…  ( 4 min )

This article is part of CSS complete tutorial by encryption-akademy and available at this link. Viewport is the area of window in which webpage is currently seen. In terms of web-browser, it is same as browser window and excludes menu bar etc. Its size varies with device, mode and orientation. In CSS there are 6 units based on viewport which are listed below. viewport width unit - vw viewport height unit - vh viewport block unit - vb viewport inline unit - vi viewport minimum unit - vmin viewport maximum unit - vmax 1. viewport width unit - vw VW stands for Viewport width. It is an unit to measure the width of viewport. VW is equivalent to percentage of viewport width. So 10vw is equal to 10% of viewport width and 100vw is full width of viewport.

In today’s tech industry, there’s a growing trend: every system is expected to be AI-powered to stay competitive. This shift has created a rising demand for engineers who not only understand artificial intelligence but also know how to build systems around it. In this blog, I’ll walk you through how to build a Retrieval-Augmented Generation (RAG) system using various language models. This is based on a project I created and the knowledge I’ve gained while learning about RAG. I’m still learning, so consider this more of a shared journey than a tutorial from an expert. RAG Most language models (like GPT-4, DeepSeek, etc.) are trained on a massive amount of data. Based on that training, they can generate responses to a wide variety of questions. However, that knowledge is static — they can’t …  ( 9 min )

In modern society, various forms of data, such as personal information, financial records, and corporate secrets, are stored and transmitted digitally. Such data is vulnerable to theft or alteration by malicious attackers. Therefore, robust security measures are essential. Data protection helps preserve the confidentiality and integrity of information while maintaining the trust of users and organizations. Symmetric key encryption is a method that uses the same key for both encryption and decryption. This approach is widely used due to its high processing speed and relatively simple implementation. However, if the key is exposed, security can be compromised, so proper key management is crucial. Symmetric key encryption forms the foundation for secure communication and data storage. AES was…  ( 5 min )

I originally posted this post on my blog a long time ago in a galaxy far, far away. I've stayed too long at stagnant jobs, and I regret it. Staying too long at jobs cost me years and thousands of dollars. I left lots of money on the table. It made some of my skills get rusty. But after connecting the dots, there were signs I failed to notice: This is the #1 sign to look for. If your daily job becomes boring, that's a sign. Or stay but diversify your sources of joy. "You can build any role you want," I was told. That happened at a past job. I rejected the idea of being a team leader. I didn't like how the role was designed at that place. It was a "wear all hats for the same pay" role. And when I brought my ideas to the table, they got rejected with a "somebody else is already kind of doing …  ( 4 min )

You're deep in the zone. Code flows from your fingers. The architecture makes perfect sense. Then your calendar notification pings: "Daily standup in 5 minutes." Your mental model of the system collapses like a house of cards. This scenario plays out thousands of times daily across development teams worldwide. The tension between necessary collaboration and focused work creates a productivity paradox that most teams struggle to resolve. The Hidden Cost of Context Switching Everything, according to recent research. Studies show that developers need up to 23 minutes to regain focus after an interruption. When you factor in the mental preparation before meetings and the cognitive residue afterward, that "quick" standup can destroy 45-60 minutes of productive time.

In SQL, JOIN refers to the function that combines two or more tables to retrieve data as a single result set. Since databases are typically designed with data separated into multiple tables for better organization and management, JOIN is essential for merging this data to derive meaningful information. It allows efficient querying based on the relationships between these separate tables. Relational databases store and manage data in multiple normalized tables. JOIN serves as a key tool that combines data from these tables based on their relationships. By using JOIN, it is possible to reduce duplication and maintain data integrity while easily integrating and retrieving data according to various conditions. This makes JOIN indispensable for data analysis and report generation. JOIN connects…  ( 6 min )

🤖 In our last article, we mastered Custom Types, creating a safety net for our test data. We learned how to define the exact shape of our data payloads and API responses.

What marine dry-docking taught me about Agile delivery in software—and how to lead both without sinking the ship. Originally published on Medium There’s a reason ships don’t run late: the plan must hold. But in software, the winds change faster. I’ve learned to sail both seas. I didn’t start in tech. I started in the engine room — where the schedules are tight, the budgets tighter, and failure is not just expensive, but dangerous. As a marine project manager, I lived and breathed Gantt charts, SMS audits, and budget-driven milestones. Timelines were sacred. Stakeholders included flag states and classification societies. Your ability to predict and manage risk was your credibility. Then I transitioned into software delivery — building life-critical safety platforms. What surprised me most w…  ( 5 min )

So against popular advice, I rolled my own auth and wanted to share. It still has a long way to go, and I absolutely do not want to compete with the SaaS providers, nor do I want to compete with big, professional packages like KeyCloak and Authentik. I just wanted to write something that was easy to use and covered most small use cases. I put together a blog post detailing the journey that led me to do something so foolish, and I hope people can relate. Github repo for microauthd. Right now, it sports a dual-server, dual-key architecture, has web, cli & JSON/HTTP (faux REST) configuration/admin interfaces, and is written in C# (.NET 8) to allow for ahead-of-time compilation (AOT). The binary sits at 26MB, the memory commit @ rest is 57MB, and startup time is sub-50ms on Windows. Linux builds are similar, if not a bit snappier. I have not yet tested on MacOS, but expect it to run fine there too. I have basic libraries for Python & Go (very basic), and testing is done via Python harness. Remember, my goal isn't to compete with the big boys; I just wanted build something solid for my use cases. That went well, so I beefed it up a bit for more general usage. I just want to put something solid out there and iterate on it until it's ready for more general use.  ( 3 min )

2081. Sum of k-Mirror Numbers Difficulty: Hard Topics: Math, Enumeration A k-mirror number is a positive integer without leading zeros that reads the same both forward and backward in base-10 as well as in base-k. For example, 9 is a 2-mirror number. The representation of 9 in base-10 and base-2 are 9 and 1001 respectively, which read the same both forward and backward. On the contrary, 4 is not a 2-mirror number. The representation of 4 in base-2 is 100, which does not read the same both forward and backward. Given the base k and the number n, return the sum of the n smallest k-mirror numbers.

When deploying AI models in enterprise environments, I’ve encountered a recurring constraint: production systems often prohibit Python runtime dependencies. While working on a compliance-sensitive project requiring local text embedding for a 10M-vector dataset, I needed a solution that could integrate directly with Java-based infrastructure. Here’s what I learned about bridging this gap using ONNX and alternative toolchains. Most open-source AI models (e.g., Hugging Face’s sentence-transformers) assume Python availability for: Tokenization (splitting text into model-digestible units) Inference (transforming tokens into embeddings/predictions) Post-processing (normalizing outputs) In my case, compliance requirements eliminated cloud API options.

I started treating the layout like fashion styling: adding a detail, removing another, trying something bold, then simplifying again. And that’s when it happened. By chance, I landed on a composition that really resonated with me. The result: A design that feels clean, vibrant, and unmistakably mine. I’m genuinely happy with it.…  ( 3 min )

1. Introduction As serverless architecture adoption rapidly grows, microservice configurations centered around AWS Lambda have become standard for many companies. However, as the number of Lambda functions grows to 10, 20, or more, an often-overlooked challenge emerges: Lambda function name management. You might think "it's just function names." However, this small issue compounds to create dozens of wasted work hours annually and risks of unexpected production failures. This article introduces the challenges of Lambda function name management in projects using the Serverless Framework and an open-source tool called "sls_enum" that solves them. By implementing this tool, you can achieve a type-safe development environment and significantly improve your team's productivity. When invoking …  ( 7 min )

The Core Idea Destructuring is a special syntax that allows you to "unpack" values from arrays or properties from objects into distinct variables. Think of it like this: You have a box (the array) with several items inside. Instead of carrying the whole box around just to get one item, destructuring lets you reach in and pull out the specific items you want, giving each one a name. Before destructuring, if you wanted to get the first and second elements of an array and assign them to variables, you would do this: const userProfile = ['John', 'Doe', 30, 'Developer']; // Accessing elements by their index number const firstName = userProfile[0]; // 'John' const lastName = userProfile[1]; // 'Doe' const age = userProfile[2]; // 30 console.log(firstName); // Output: John console.log(…  ( 5 min )

Hey everyone! Welcome to the very first post in our new series, "One more block, please!". As you already know, my name is Borba, and for the last five years, my life has revolved around one great love: Software Engineering.

Permanent Credentials: IAM Users are assigned long-term credentials, such as a username and …  ( 6 min )

👋 Introduction Let’s dive into the formal problem definition to see how this works: You're given two integers: k: the base in which we check for palindromes n: the number of k-mirror numbers to find A k-mirror number is a positive integer that: Is a palindrome in base-10 Is also a palindrome in base-k Your task: return the sum of the first n such numbers. This is a palindrome-generation and filtering problem. The challenge lies in generating candidate numbers efficiently and checking their representations in different bases. Key Observations: Not every decimal palindrome is a k-palindrome (i.e., palindrome in base-k) Instead of checking all numbers, generate only palindromes in base-10 (which drastically reduces search space) For each generated number, convert it to base-k and check i…  ( 5 min )

I've been hearing a lot about these new AI video models that look incredibly realistic lately. People are actually creating entire TikTok channels based on them, and they look surprisingly good! I never really tried them myself, so I wanted to check them out. I decided to start with Google's VEO3 model that everyone seems to be talking about. Instead of manually creating prompts and videos one by one, I developed an AI automation that will take any topic you have and turn it into banger videos. This way, I could quickly test the model's capabilities and see if it lives up to the hype. So in this tutorial, I'll walk you through how I built this automation to: Generate creative video ideas from a simple topic input Craft optimized prompts for Google VEO3 Produce high-quality AI videos wi…  ( 9 min )

TypeScript Best Practices TypeScript is the foundation of Angular applications. Clean, type-safe code reduces bugs and enhances maintainability. Enable strict mode in your tsconfig.json to catch potential issues at compile time. { "compilerOptions": { "strict": true } } Let TypeScript infer types when the type is obvious, to reduce verbosity: const name = 'Angular'; // inferred as string any; Use unknown Instead Using any disables type checking. If you must accept uncertain data, prefer unknown and refine it safely: function process(data: unknown) { if (typeof data === 'string') { console.log(data.toUpperCase()); } } Angular has shifted away from NgModules in favor of a simpler, more streamlined approach using standalone components. Standalone components are easier t…  ( 5 min )

The UK startup ecosystem has seen an intriguing shift in recent years. While classic tech functions continue to be paramount, there's a new contender that's remaking the way founders tackle product building: the artificial intelligence developer. This is not another technology fad, it's evolving into the secret sauce that distinguishes scaling startups from those mired in neutral. The New Partnership Dynamic Beyond Basic Implementation The Strategic Advantage Building for Scale The Investment Perspective Future-Proofing the Business Maybe most significantly, UK entrepreneurs are employing or looking to hire artificial intelligence developers to future-proof their ventures. As artificial intelligence permeates every corner of business, those that lack intelligent systems risk obsolescence. An artificial intelligence developer assists start-ups in keeping ahead of this curve and developing AI strategies which make them innovators, not imitators. The union of UK founders and AI creators is not just a recruitment choice, but a strategic one that can make or break whether a startup succeeds in an increasingly AI-based economy. Those who adopt this alliance early are creating tomorrow's market leaders today.  ( 4 min )

TL;DR: NieR mastermind Yoko Taro—famous for his off-the-wall antics and games like Drakengard, NieR and NieR: Automata—says modern AAA studios just aren’t as weird or daring as they used to be. Thirty years in the biz has shown him that big budgets breed risk aversion, so unusual creators get sidelined. Meanwhile, the strangest, most inventive ideas have migrated to the indie scene (think Undertale, Doki Doki Literature Club, Disco Elysium), where low costs mean high weirdness. Yoko even wonders if his own quirky style is the reason we’re still waiting on a true Automata sequel—AAA publishers might just be too scared to fund all that oddball brilliance.  ( 3 min )

TL;DR Prophesee’s neuromorphic “event” cameras ditch full‐frame captures and instead only report pixel‐level brightness changes, slashing power draw (just 2 mW active, 16 µW standby) while pumping out >1 kHz updates with sub-1 ms latency. That combo makes them ideal for always-on AR glasses—boosting battery life, speed and even privacy (no full-image eye snaps). At AWE the author tried out Prophesee’s eye-tracking demo (built with 7Invensun): a pair of IR LEDs + tiny event cameras mounted on specs, a quick three‐point paper calibration, and boom—the on-screen orange “gaze dot” nailed every gaze shift. Accuracy claims are <1° and it felt snappy and reliable, making these sensors a compelling contender for next-gen, low-power AR smartglasses.  ( 3 min )

Introduction It all started in day while I was smashing buttons on my Atari. I was playing pong when I realized this game was very simple I could make it myself. That's when I talked with my dad and he showed my AWS Q CLI AI. Although I didn't know how to code this, AI did for me. Setup Although the AI would write the code I would have to test it plug it in and add tweaks and fixes. So first I download all the stuff in order to do this using Ricardo Sueiras's guide (https://dev.to/aws/the-essential-guide-to-installing-amazon-q-developer-cli-on-linux-headless-and-desktop-3bo7?trk=c09e10a1-6feb-4902-897f-846979733114&sc_channel=blog ). Finally I downloaded AWS Q CLI AI and paired it with pygames. Now my first step was to tell my prompt to the AI. The AI coded it form me and I was ready except for the fact it didn't really work. Here the bot is bugging out and glitching the ball causing it to stop moving as it is stuck on the bot. Tweaking I realized while testing that the bot was well unbeatable and I knew I had to make it a little slower or easier to beat so I told the AI to tweak the code and make it so the AI would be beatable and I also had it so once someone got to 11 points the would win. After this change, I plugged in the new code and tested only to realize there where a lot of bugs within this code. Here the bot is glitching and unable to move so I had the AI fix it. Finally the bot is perfect and I even got the win! Conclusion After a little bit of time and help of AI I was able to make my first ever game a pong remix and I felt proud. This was a unforgettable day I had picked a new productive hobby and managed to not be lazy. I really recommend to do this yourselves. Thank you.  ( 3 min )

Understanding Basics Bash for Beginners Have you ever wondered what those cryptic commands you see in movies or on developer’s screens actually do? Chances are, many of them are Bash commands! Bash (Bourne Again SHell) is a powerful tool that lets you interact with your computer’s operating system. It’s especially important for developers because it allows you to automate tasks, manage files, and run programs efficiently. Understanding the basics of Bash is a common expectation in technical interviews, and it will significantly improve your workflow as a programmer. Think of Bash as a translator between you and your computer. You give Bash instructions in a specific language (Bash commands), and it tells your computer what to do. It's like giving instructions to a robot – you need to b…  ( 5 min )

Most of us working on side projects or building in public hit a weird friction point early on: Link-in-bio tools fix that, but most of them feel like they were built for lifestyle influencers, not indie devs or technical creators. They’re bloated, closed, or weirdly expensive. So I decided to rethink how I handled mine and what I ended up using saved me from building a whole separate landing page. What I wanted from a dev-friendly bio link setup Customizable but fast to set up Clean, no bloat Analytics I could actually use Multiple pages under one account (for personal vs project profiles) A way to share links across different audiences/platforms Ideally, open to tracking by device or country Carrd was close, but still required design effort. What I landed on: Linkx.ee Linkx.ee while browsing some creator tool lists. It checked the right boxes from a dev perspective: No-code setup with the option to go deep if you want Fast page loading QR code generator (surprisingly useful at conferences or meetups) Device- and geo-based link targeting Works with webhooks and can plug into analytics pipelines You can run multiple profiles (great if you want to separate open source from paid projects) It also gave me a clean public-facing page without needing to spin up a static site or configure a reverse proxy. For side projects, MVPs, or just linking from your GitHub profile, it’s kind of perfect. If you’re a developer who doesn’t want to manage yet another frontend just to share links to your work, a solid link-in-bio tool is surprisingly useful. And if you’re like me someone who likes performance, metrics, and clean interfaces you might want to skip the mainstream stuff and give Linkx.ee a try. Linktree and Koji felt too influencer-y.  ( 3 min )

When our team first started the Agent Development Kit Hackathon with Google Cloud, we were driven by a single, nagging question: Why do today's powerful AIs feel so... passive? They are brilliant calculators, but they often feel like a "polite guest who won't speak until spoken to." We wanted to build a true partner—an AI that could feel alive. One that could get curious with you, understand the flow of your thinking, and have an "inner life" of its own. That idea became Wise. In just under two weeks, we built and deployed a working prototype of a system that we believe represents a new paradigm for human-AI interaction. This is the story of how we built it.

WHAT IS CONTAINERIZATION? Containerization is a method of packaging an application along with its dependencies, libraries, and configuration files into a single unit called a container. This ensures that the application runs consistently across different computing environments. In software engineering, containerization is operating-system-level virtualization or application-level virtualization over multiple network resources so that software applications can run in isolated user spaces called containers in any cloud or non-cloud environment, regardless of type or vendor. Containerization is a software deployment process that bundles an application’s code with all the files and libraries it needs to run on any infrastructure.

🔒 Dymo has identified a critical vulnerability affecting the Public Prosecution Office of the Sultanate of Oman. Our monitoring systems detected unauthorized access to their email servers, which are currently being exploited to send fraudulent cryptocurrency-related campaigns. These emails are dispatched from legitimate addresses within the institution, granting them apparent authenticity and making detection by conventional security filters difficult, thereby significantly increasing the risk to potential victims worldwide. This is not the first time we have uncovered such an incident. Several months ago, we reported a similar vulnerability in the highest police authority of Ecuador, which also allowed malicious actors to misuse official infrastructure for illicit purposes. These cases reveal a worrying pattern of weaknesses in protecting critical infrastructures within governmental organizations across different countries. The vulnerability has been formally reported to the Public Prosecution Office of the Sultanate of Oman, along with a series of technical recommendations to mitigate the breach’s impact and prevent future exploitation. At Dymo, we reaffirm our commitment to global cybersecurity and responsible disclosure of vulnerabilities that threaten the integrity and trust of public and private institutions worldwide. Incidents like these highlight the urgent need to strengthen protective measures in state organizations increasingly exposed to cyber threats.

Why I introduced This DevOps Definition 🎯 The Realization Behind the Definition What This Definition Truly Embraces 🔮 Why This Definition Matters — Now and In the Future This definition matters in 2025 and beyond because: 📘 See the official GitHub repo: https://github.com/sresrinivas/etoe 📌 The Final Thought DevOps isn't a title. It's not a tool. It's a discipline that unites engineering depth in systems and applications — and this is the definition that will shape the future of DevOps engineering.  ( 4 min )

Users can track all the dares they have accepted and those they have declined, keeping their challenge history organized. Building this feature involved creating dynamic lists and managing state efficiently so the data updates in real-time. It also taught me how to handle edge cases, like re-accepting or revisiting old dares. #StateManagement #ReactNative #UserExperience  ( 2 min )

"Your CRUD app is a ticking time bomb. Here’s how to defuse it—without a rewrite." Legacy systems are like old houses: Every change risks breaking something No one remembers why the plumbing works this way Adding a new room feels impossible But migrating to event sourcing doesn’t require burning it all down. Here’s how we moved a 500-table Rails monolith to event sourcing—one component at a time—without downtime. Phase 1: Lay the Foundation Step 1: Identify the Pain Points Start with the highest-value, highest-pain areas: Audit-heavy domains (payments, user access) Complex workflows (order fulfillment) Frequent "how did this happen?" debugging Avoid: Static reference data (e.g., product catalogs).

It integrates with calendars, messaging tools, and local event sources to deliver relevant and timely scheduling help. run How I Used Runner H Using Runner H, I created a scheduling automation pipeline that: Aggregates inputs from school calendars, extracurricular signups, and family messages Automatically suggests family activities and books tickets or registers as nee…  ( 4 min )

In this blog post, we’ll explore how to automate AWS infrastructure provisioning using CloudFormation templates orchestrated by Jenkins pipelines. We'll build a web server environment deployed across three stages: development, staging, and production, following a CI/CD approach. This post builds upon the previous blog where we detailed setting up a Jenkins server on an EC2 instance and configuring it with essential plugins. We’ll now use that Jenkins server to drive infrastructure-as-code (IaC) workflows using AWS CloudFormation. The high-level architecture for this solution involves: A Jenkins server deployed on an EC2 instance in a public subnet. A Git repository containing the CloudFormation templates for creating network and compute resources. An S3 bucket to store the templates for ne…  ( 8 min )

For 16 years, I worked as an independent contractor for the company that marketed and sold websites under the BankSITE® brand. In 2022, I began building a new proprietary WordPress-based software system that would eventually become the foundation of BankSITE® Builder Pro (BBPro). That framework now powers over 100 live financial institution websites across the United States. Behind the name and brand was a single developer: me. My name is Bojan Josifoski, and I am the sole creator and author of the BBPro Core Framework. From 2022 to 2025, I designed, built, and maintained this proprietary platform in its entirety—including: Software architecture Full-stack development Update and deployment systems Version control and optimization There was never: A written employment contract A copyright assignment A license agreement In 2025, I registered the BBPro Core Framework with the U.S. Copyright Office under Case #: 1-14944175091. This was not an act of hostility, but a necessary step to preserve authorship and protect the continuity of a platform relied upon by over 100 U.S. banks. BBPro was never open source. It was not work-for-hire. It remains privately held and unlicensed. The BBPro software platform is protected by copyright and was never assigned or licensed to BankSITE® Services or any third party. I am open to ethical and legal solutions that support long-term continuity and compliance for institutions using BBPro. But I will no longer remain silent or invisible.

Biometric Authentication: Enhancing Security with Endpoint Protection and One-Time Passwords Biometric authentication has emerged as a powerful method of securing digital systems in an age where cyber threats are increasingly sophisticated. By using unique biological characteristics such as fingerprints, facial recognition, iris patterns, or voiceprints, biometric systems offer a more secure and convenient alternative to traditional password-based authentication. As digital transformation accelerates across industries, integrating biometric authentication with endpoint security and one-time passwords (OTPs) has become a crucial strategy for comprehensive protection.

Let me be honest — I wasted a lot of time trying to learn data analytics on my own. I started with free YouTube playlists, then bounced between Coursera, Excel crash courses, and random blogs. Each platform had a piece of the puzzle, but none of them really helped me connect the dots or stay on track. I needed something beginner-friendly, job-focused, and structured. After going down multiple Reddit and Quora rabbit holes, I enrolled in the Coding Ninjas Data Analytics Job Bootcamp. I wasn’t expecting miracles, but it turned out to be one of the more practical, real-world programs I’ve come across. What I Was Looking For in a Course A practical skill set to land a data analyst job Real projects I could add to my resume Mentorship and placement help A schedule that worked alongside my full-time job After weeks of comparing options like Scaler, Simplilearn, and Great Learning, I felt like most were either too expensive or overloaded with fluff. That’s when Coding Ninjas caught my eye—specifically their data analytics job bootcamp. What My Experience Has Been Like So Far Beginner-Friendly but Not Oversimplified Tons of Practice + Capstone Projects Placement Support That Isn’t Just a Gimmick A Few Things That Could Be Better The earlier Excel and SQL modules felt a bit slow if you’ve used them before. You still have to hustle—this isn’t a shortcut to a ₹10LPA role overnight. Final Thoughts: Is This the Best Data Analytics Course in India? You’ll still need to stay consistent and put in the hours, but if you do, you’ll come out of it with a solid portfolio, interview prep, and real-world confidence. No regrets here—and finally, I feel like I’m not just “learning,” I’m actually moving toward a job.  ( 4 min )

When I started building GenAI solutions, I felt confident working with models, prompts, and architecture — but the data part always felt like a black box. I kept asking myself: Where do I even begin if I want to use my own data? Every time I looked into it, I found a pile of scattered advice, incomplete setups, or tools that didn’t quite fit together. It reminded me of moving into a new house and opening the garage — only to find it packed with boxes from ten different people. You know there’s valuable stuff in there, but it’s all mixed up, mislabeled, and overwhelming. This post is what I wish someone had handed me back then — a clear, hands-on walkthrough of how to turn that chaotic garage into a well-organized workshop.

Recently I had to test a scenario where the laravel application detects which region a request is coming from and based on that chooses the correct payment gateway (domestic/international) to effect the payment. This was tricky for the following reasons: We were testing on servers which were in a VPN enclosed environment. And the VPN gateway always shows a United States IP. All gateways available to us were US based only. Using a different VPN wasn't possible as its against company policy (and also unsafe). Now normally, when such systems are built, they are usually built on the basis of geolocation (invasive, think of your browser asking you to share your location) or on the basis of IP Ranges (non-invasive, you can find these on many websites that tell you that you are from such and such…  ( 3 min )

As soon as I got a Keychron K10 Pro, I started to wonder what to do with those extra 4 keys on the corner. First, of course, I needed some cooler keycaps than square/circle/triangle/cross.

Hey everyone! Who doesn’t love a good puzzle game to pass the time — whether you're in line, on the bus, or anywhere else? That’s exactly why I decided to create Elementar! I was inspired by classic logic games like Tohu wa-bohu and even the famous LinkedIn Tango, but I added some unique twists and exclusive modes to make the experience even more fun and engaging! The core challenge is simple: fill the grid with an equal number of Fire 🔥 and Water 💧 symbols in each row and column. But watch out — you can’t place 3 of the same symbol in a row, either horizontally or vertically. That’s the golden rule! And the best part? I built Elementar as a Progressive Web App (PWA), so you can install it directly on your phone and play offline anytime — or just open it in your browser! 📱💻 You’ll find the full rules and mode details on the game’s page. Try it out and let me know what you think! 👉 Play Elementar now: https://elementar.vercel.app Got ideas for new modes, improvements, or puzzles you'd love to see?

When you’re building a feature-rich application that relies on Redis, naming your keys might seem trivial at first. But as your system grows, poorly named keys can become a mess—leading to bugs, data collisions, and serious maintenance headaches. That’s why it's important to follow clear and consistent naming conventions in Redis. The goal is to make your data structures not just usable, but self-explanatory. You want anyone looking at the data to instantly understand what a key represents, what kind of data it holds, and how it's organized. Redis doesn’t enforce a structure in key names, but you can create one yourself using colons : as separators. Example: user:1001:settings user:1001:cart order:20230621:items This naming style is both readable and machine-friendly. It acts like a pseud…  ( 4 min )

When working with AWS CDK in environments where OpenID Connect (OIDC) is used for role assumption—especially in CI/CD pipelines—developers often encounter cryptic permission-related errors.

It is created by joining two separate tables using a selected column that has similar information on both tables. The table selected first is the fact table and the other table is the dimension table. There is a primary key in one table which is the unique identifier that maps on to the foreign key in the other table. There are four types of relationships: i)One to One Consider two tables; one with sales date and another with calendar dates. The sales date can only match with one date on the calendar table, this creates a connection between the two tables based on these columns. ii)One to Many When you have customer table with customer id and sales table with customer id, the customer ID can match the sales table multiple times. This is because one customer can have multiple sales creating a one-to-many relationship. iii)Many to One For example, table with Sales information and another table with Products information. The common column between them is the product ID column. In this case, there are multiple sales that are made of one product. Therefore, multiple values on the sales table match with one value on the product table. iv)Many to Many Another thing about relationships is the cross-filter direction. This refers to the direction in which a filter that is applied on tables that have a relationship affect those tables. Relationships in PowerBI have made it easy to understand, explore and join tables for easier visualization of data and I can't wait to learn more!  ( 3 min )

Hey Devs 👋 Over the past few months, I’ve been building my solo SaaS project and wanted to share some reflections — especially about the tech stack I chose. While most indie hackers lean on lightweight setups like Node.js or Python, I decided to take a less-traveled path: combining Next.js and Spring Boot. Here's why I went with this setup — and what I learned along the way. Even though my backend is built with Spring Boot, I still made full use of Next.js’s server actions and full-stack features. Rather than calling the Spring Boot API directly from the browser, I routed all API calls through Next.js server components. This approach gave me: ✅ Server-side execution only (no client-side leaks) ✅ Invisible API calls in the browser network tab ✅ No CORS headaches This helped me build a more…  ( 4 min )

Legacy Contracts, Stuck in Time Why Do We Need Smart Contracts 2.0? Perception — the ability to sense changes in environment or state Memory — the ability to store and apply interaction and state history Agency — the ability to act proactively toward a goal without being called Adaptation & Evolution — the ability to adjust strategy based on experience or feedback Today’s smart contracts cannot remember past interactions, cannot initiate actions on their own, and cannot adjust their behavior based on long-term signals—whether on-chain or off-chain. This gap calls for a new primitive: a transition from function-based contracts to agent-based contracts. This isn’t just an upgrade in architecture—it’s a fundamental paradigm shift. At SeaOS, we define Smart Contracts 2.0 as: On-chain agents th…  ( 5 min )

All it takes is 5 minutes, you won't even need most of the text that's on here. Custom Domain -> I bought my custom domain at godaddy.com but you can also use other services such as hostgator.com, domains.cloudflare.com, namecheap.com. However, I did later find out that Vercel's pricing was lowest for the domains I was interested in. Your website -> Have it parked in a repo on http://github.com/ Hosting -> I used Vercel as it's FREE.99! (see their hobby tier) Go to vercel.com & register if you don't have an account just yet. Add a new project: Import your project and follow instructions to "Deploy", and you'll see "Adding a domain" as one of the next steps. Here you have a choice of buying or adding a domain. Type in the name of the domain you bought. Vercel will generate something like below for you. It might be multiple entries. Unless you bought your domain on Vercel, go to your domain provider to access DNS records configurations. For godaddy it's in here: https://account.godaddy.com/products Scroll down to your domain, click "DNS" and plug the values that Vercel generated for you there. Then go back to Vercel and click "refresh" on those generated entries. Ta-da! 🎉 Your portfolio should now be up and running.  ( 3 min )

Hey Dev Community 👋 I recently launched The Mindloom — an AI-powered mental wellness platform designed to make emotional support more accessible, reflective, and human. This wasn’t just a product build for me — it was a deeply personal journey as a builder and a thinker. It started with a simple thought: therapy helps, but access is hard. Scheduling sessions, costs, and most importantly — the fear of being judged — can hold people back. What if an empathetic, always-available AI companion could help people check in with themselves, journal openly, and feel heard? That seed turned into The Mindloom. I chose Next.js 15 as the foundation, combined with Supabase for database and auth (via Clerk), Upstash for vector embeddings, and ElevenLabs for voice interactions. The AI backend uses OpenAI'…  ( 3 min )

Some routes in your application require authentication or other conditions to be met before users can access them. TanStack Router provides a powerful guard mechanism to handle these scenarios through the beforeLoad function, which allows you to intercept route navigation and enforce access control rules before any components are rendered. When you define a route with createFileRoute you have can specify a function in the beforeLoad property. This function will be called before the route is loaded, allowing you to perform checks and potentially redirect the user if they don't meet the required conditions. An example: import { redirect, createFileRoute } from '@tanstack/react-router'; import { isAuthenticated } from '../utils/auth'; export const Route = createFileRoute('/profile')({ comp…  ( 5 min )

Why You Should Start Using a Clipboard Manager Today You copy something important, copy something else... aaand it's gone. Ever lost a long message you spent 10 minutes writing? Had to keep switching between apps to re-copy five different values? Or filled a long form just for the browser to refresh and for you to lose all the work you've done? We've all been there. That’s where clipboard managers come in - saving your day (and your sanity). A clipboard manager is an app that, well... manages your clipboard. Every time you copy something (Ctrl+C / ⌘+C) - it's saved in a special place among the stars called "the clipboard". When you paste (Ctrl+V / ⌘+V) - the most recent item from the clipboard is pasted in the foremost app. By default - your clipboard only remembers the last item you co…  ( 5 min )

Computers can't perfectly represent most decimal numbers! YES! You read that right...even I was like,"Wait, what? That can't be right!" But then I remembered this crazy story about Airane 5 explosion because of a tiny decimal point error, which I saw on an IG reel. Hence why precision matters! We naturally work in decimal (base-10) while computers use binary (base-2) arithmetic, This simple difference creates complex problems. For example, the seemingly simple number 0.1 becomes an endless sequence in binary: 0.00011001100110011... and 0.1 + 0.7 ≠ 0.8 To solve this complex problem of having a precise value IEEE 754 was introduced.

Some topics don't require code. Just courage. In tech, we often talk about building bridges between systems, teams, and communities. But sometimes, the bridges that matter most are the ones we build quietly between people. What happens when you offer someone your trust, your time, your effort, and they simply let go? Not every betrayal is loud. Sometimes it's a message left on read, a tone that changes, a silence that grows until you realize you're the only one still standing on what you both started. This isn’t about blame. It’s about recognizing when something shifts and deciding what to do with what remains. If this speaks to something you’ve felt, I wrote a story that might resonate.

Some days I feel unstoppable—deep in the zone, code flowing, tabs organized, energy locked in. Other days… it’s 4 PM, I’ve bounced between Slack, VS Code, Notion, and six Stack Overflow threads—and I can’t tell you what I actually finished. Being a developer comes with freedom. But no one talks enough about the pressure that freedom brings. Time is weird in this work. I used to think being constantly active meant I was making progress. But now, I catch myself asking: “What actually moved forward today?” Some days, the only real win was deleting code that no longer served a purpose—and that’s okay. There’s something powerful about a solid 2-hour coding window—no notifications, no background noise, just solving. Those moments don’t happen by accident. And they don’t happen every day. But when they do, they remind me why I started coding in the first place. I’ve tried Pomodoros, strict schedules, even time blocking. Sometimes they work. Other times, I need flexibility more than structure. The trick—for me, at least—is knowing which version of me is showing up that day. And adjusting without guilt. Burnout doesn’t always come from shipping too much. Sometimes it comes from staring at the same problem too long, getting nowhere, and losing the joy of the work. That’s when I step away. I don’t “quit”—I just give myself space to come back stronger. Some weeks I feel aligned. Others, I feel scattered. But I’ve learned to check in with myself—not just my code. “Am I creating, or just reacting today?” “Am I learning, or just collecting tabs?” “Do I feel behind—or just tired?” That’s made all the difference. How do you manage your time without losing momentum? Have you found a rhythm that works for you—or are you still figuring it out like me? What makes you feel in control of your time as a dev? Drop your thoughts. Let’s talk about the messy, honest side of productivity—no hustle posts, no hacks, just real dev life.  ( 4 min )

Given a large body of text, we (or in this case the systems we build) try to summarise the important points into a concise paragraph. Historically, the ways in which summarisation systems are categorised are numerous, but they essentially fall into two broad types: Extractive summarisation essentially treats it as a classification problem, where each sentence is considered as a binary classification problem, where 0 implies the sentence is not included in the final summary and 1 otherwise.

Signals in Angular 20 fundamentally simplify reactive programming by offering a lightweight, synchronous, and intuitive way to manage state changes in the application.

Our existing validation logic, focused on schema and data types, missed this semantic constraint. The incident highlighted a critical gap in our defensive programming strategy.

We need something better than pip — and that's where uv comes in. It’s a fast Python package manager and task runner that replaces pip, venv, and even parts of poetry, without the extra overhead. Though previously I wrote Do not use 'pip freeze' and Best way to create requirements.txt. You can read them... uv You can find the installation instructions for uv here uv init: Instant Project Setup uv init This command creates a boilerplate pyproject.toml and sets up your .venv — no manual steps needed. It automatically detects your Python version and prepares a minimal project environment. Need a package like rich? uv add rich This adds it to your pyproject.toml, installs it, and updates your uv.lock. No need to touch requirements.txt. Example usage with rich: from rich import print print("[bold green]Hello from UV-powered project![/bold green]") Instead of manually activating .venv, use: uv run main.py This runs your app inside the managed environment automatically. Yes, you can still run with python main.py, but that means you'll have to activate .venv manually: source .venv/bin/activate First run uv venv and then install all packages from pyproject.toml uv sync There’s more you can do: uv pip, uv pip freeze, uv sync --update, and more. You can even change Python versions or set a specific version in .python-version — check it out in their docs.  ( 3 min )

No, AI didn't take my job. It enhanced it. When ChatGPT first came out, I was skeptical. Those early prompts really surprised me — the results were good, although I also noticed some hallucinations and answers disconnected from reality due to the training data cutoff. That frustrated me at first, but I quickly understood why, and it became a secondary issue. Then the paid version launched. At first, I hesitated — it felt expensive — but I decided to give it a shot. I quickly integrated it into my workflow and, to my surprise, saw a meaningful boost in productivity. I think many of us have gone through similar phases. Now, I can’t imagine canceling the subscription or removing this tool from my day-to-day. And I’m not just talking about ChatGPT — I mean AI in general. I entered a spiral — w…  ( 4 min )

Over the last couple of weeks, I have had to upgrade some function apps which were written about 6 years ago. These function apps were triggered by logic apps and in most cases, the original implementation invoked the function apps via http connectors. It got me thinking about using http connectors but incorporating swagger definitions. Incorporating swagger definitions provide a better UX for integrating with function app. To start off, the function app code has to be annotated with openApi attributes and for c# projects the nugget package must be added. The nugget package to use is Microsoft.Azure.Functions.Worker.Extensions.OpenApi":Version="1.5.1" In the scenario been discussed, a shipping notice will be created. The shipping notice request will be defined by a ShippingNoticeDTO. names…  ( 4 min )

🧠 Solving LeetCode Until I Become Top 1% — Day 27 🔹 Problem: 2138 Divide a String Into Groups of Size k Difficulty: #Easy Tags: #String, #Greedy Given a string s, divide it into groups of size k. If the final group is smaller than k, fill it with the given fill character until it reaches length k. Return a list of strings, each representing a group of size k. Brute Force Idea: Start taking substrings of length k in a loop and append them to a result list. If the final group is smaller than k, pad it manually. Optimized Strategy: First, check if s is divisible by k. If not, append the appropriate number of fill characters to make its length divisible by k. Then, iterate over the updated string with a step of size k and slice out chunks. class Solution: def divideString(self, s: str, k: int, fill: str) -> List[str]: res = [] n = len(s) s = s + (fill*(k-n%k) if n%k else '') start = 0 while start < len(s): res.append(s[start:start+k]) start += k return res Time: O(N) Traverses the string once to pad (if needed), and once to slice. Space: O(N) Output list stores all the k-sized chunks. ✅ Learned how to chunk a string cleanly using modulo logic and list comprehensions. 💡 Edge cases like "what if the string isn't divisible by k?" must be handled before chunking. 💭 This pattern is helpful for problems involving grouping, formatting, or padding strings to meet constraints.

No, la IA no me quitó el trabajo. Me lo potenció. Cuando salió ChatGPT y lo probé por primera vez, era escéptico. Esos primeros prompts me sorprendieron bastante: los resultados eran buenos, aunque también noté alucinaciones y respuestas algo desconectadas de la actualidad, debido al desfase entre la información con la que fue entrenado y el presente. Esto me frustró al principio, pero pronto entendí el porqué y lo convertí en un problema secundario. Cuando apareció la versión de pago, dudé en suscribirme. Me parecía cara, pero decidí darle una oportunidad. Rápidamente lo integré en mi workflow y, para mi sorpresa, noté un aumento en mi productividad nada despreciable. Supongo que muchos hemos pasado por estas fases de forma similar. Hoy por hoy, me resulta impensable cancelar la suscripci…  ( 4 min )

Your GitHub Actions Secrets Are the Weakest Link in Your AWS Security Chain Are you still using AWS access keys and secrets to authenticate your GitHub Actions with AWS in 2025? Please don't. Unless you want to wake up someday with 1000 GPU machines mining Bitcoin in your account at your expense, footing a million-dollar bill. Using long-term secrets can be a security nightmare that could expose your cloud account to a possible security incident. You might be just one exposed GitHub secret away from an AWS billing catastrophe. You should use OpenID Connect (OIDC), a modern, more secure way to authenticate your GitHub Actions workflows with AWS without storing long-lived credentials. You can configure the OIDC to work with certain GitHub org and GitHub repos, or you can go more granular and…  ( 9 min )

Microservices promise flexibility, scalability, and faster deployments. However, without proper communication strategies, they quickly become a tangled web of tightly coupled services, frequent downtime, and frustrating bugs. In this article, we’ll explore common microservice communication problems and how to fix them by adopting modern patterns and tools. Imagine a typical e-commerce application with services like OrderService, PaymentService, and InventoryService. A direct HTTP call chain might look like this: OrderService → PaymentService → InventoryService Now, suppose InventoryService goes down.

Overview TypeScript is an object-oriented programming language developed by Microsoft in 2012. It is a superset of JavaScript, extending its functionality by adding data types, classes, and other object-oriented features along with type-checking capabilities. While JavaScript is ideal for small-scale applications, TypeScript is better suited for larger projects. It can be used to develop JavaScript applications for both server-side and client-side execution. TypeScript can be likened to JavaScript, but with a stricter and more organized approach. If JavaScript is your easygoing companion, TypeScript is the disciplined soldier in your coding journey. While both are capable languages for web development, TypeScript adds a layer of structure and order, making it ideal for managing large-sca…  ( 5 min )

Troubling Situation Isn’t that a bit strange? Even today, many AI startups are still focused on perfecting their chat interfaces, as if a better text box alone could unlock the future of interaction. But is that really the best we can do? Modern language models already understand complex intent — that’s no longer the bottleneck. The real challenge is that we haven’t given them a true environment to act in. Our entire digital ecosystem is still built on a core assumption: that the world is made for humans. Webpages, buttons, input fields — all designed with the idea that a person is sitting there, manually initiating and completing tasks. But if we begin to seriously imagine a world where AI is the primary actor — where agents collaborate, make decisions, and carry out tasks — then these tr…  ( 9 min )

KEDA is an open-source cloud native project under CNCF that enables Kubernetes to scale applications based on the events they consume. By leveraging event-based scaling, KEDA empowers Kubernetes to automatically adjust the number of running instances of a containerized service in response to external events, such as messages in a queue or an incoming request from an event stream. This dynamic scaling approach optimizes resource utilization and ensures that applications remain highly available and responsive. KEDA stands for Kubernetes Event-Driven Autoscaling.

Introduction: Today, I encountered a frustrating but educational error while working on a Spring Boot project in Eclipse. The error message read: "One or more constraints have not been satisfied. Utility Module and Dynamic Web Module 6.0 cannot both be selected." If you're new to Spring Boot or Maven, this might confuse you — here’s what it means and how I resolved it. Spring Boot is designed to run as a standalone JAR with an embedded server (like Tomcat). It doesn't need or support legacy Java EE modules like the Dynamic Web Module. Eclipse, however, sometimes misinterprets your project structure and adds these facets automatically, causing conflicts like: Dynamic Web Module cannot be removed Utility Module conflicts with Web Module Spring Boot controllers not working Delete Eclipse’s Facet Metadata: .settings/, .project, and .classpath from the project folder Re-import Project: File → Import → Maven → Existing Maven Project Ensure Correct Maven Configuration: jar Run the Project with: mvn spring-boot:run OR Run As → Java Application on your main class Fix the Controller: java @Controller public class HomeController { @RequestMapping("/") @ResponseBody public String home() { System.out.println("Hit HomeController"); return "Welcome to Spring Boot!"; } } ### 🔎 Lesson Learned: * Don’t use `Dynamic Web Module` with Spring Boot * Use embedded server – not external WAR deployment unless required * Always check controller method return types and annotations * Spring Boot thrives on simplicity — don’t force Java EE structures into it ### 💬 Final Words: I faced this issue for hours and now fully understand why Spring Boot doesn't need the overhead of servlet container configuration. If you're facing the same — **delete Eclipse metadata, use pure Maven, and let Spring Boot do its magic.**  ( 3 min )

Introduction Last year, I began my journey into Java programming. Like many students, I focused mainly on what was taught in the university syllabus—just enough to pass exams. I didn’t explore Java deeply, nor did I truly understand how to approach learning programming as a skill, rather than a subject. Now, I’ve decided to start over, not because I failed, but because I finally understand what I want—to become a professional Java developer who writes clean, working code and can build real-world applications confidently. When I first learned Java, my focus was limited to: Clearing university exams Memorizing definitions and syntax Completing assignments just to get grades I built a small project using Servlets, JSP, and Hibernate, but deep down, I felt unsure about how much I actually un…  ( 4 min )

Ever wondered how AI tools like ChatGPT, Siri, or Grammarly understand what you are saying and respond like a human? That’s all thanks to Natural Language Processing (NLP), a branch of Artificial Intelligence (AI) that helps machines make sense of human language. NLP sits at the intersection of computer science, linguistics, and deep learning. It’s the reason why AI can translate languages, summarize articles, answer questions, and even chat with you (chatGPT 😆). As a subfield of Deep Learning, NLP uses neural networks to process and generate human language in a way that feels surprisingly intelligent.

We’ll explore how Bloom filters reduce shuffle volume, improve query performance, and impact ove…  ( 6 min )

"There’s a new JavaScript framework every week." A 2024 survey of over 70,000 developers by Stack Overflow found that 60% of developers feel overwhelmed by how fast the tech industry evolves. Between React, Svelte, Qwik, Bun, Astro, Rust, Go, and a dozen more tools that popped up last month — it’s easy to feel like you're always behind. But here’s the truth no one tells you: You don’t need to learn everything. Let’s break it down. It’s a trap. You start learning React, then someone on Twitter says, “React is dead, learn Solid.js!” You're halfway through a Node.js course, and someone posts, “Why I switched from Node to Rust and never looked back.” You spend weeks learning Docker, only to see a new tool with a cooler logo take over the headlines.

What is DIP? Dependency Inversion Principle is one of the SOLID Principle. It states that High Level Module shouldn't depend on low level modules, Both should depend on abstraction. Means, the code that handles business-logic shouldn't depend directly on the implementation details. Instead they both should depend on interfaces/abstract Class. Suppose we have to 2 Modules,Car Module and Engine Module and Car Module uses Engine Module. Now if we are using DIP then we can swap Diesal Engine to Petrol Engine. Otherwise I have to make changes in the Car Module also. We can do this using either interface injection or abstract class injection.

How to Create Your Own Laravel String Helper Method Using a Macro Ibrahim Al Anshor ・ Jun 22 #laravel #php #webdev #programming  ( 2 min )

Laravel's String helper offers many useful methods you can use in your application. We can also create our own laravel string helper method using a macro. For example, I want to create a randomSlug method that turns a string into a slug and appends a random string. use Illuminate\Support\Str; Str::macro('randomSlug', function ($slug, $length = 6) { return Str::slug($slug . ' ' . Str::random($length)); }); To use the method throughout your Laravel application, register the macro in the boot method of AppServiceProvider. <?php namespace App\Providers; use Illuminate\Support\ServiceProvider; use Illuminate\Support\Str; class AppServiceProvider extends ServiceProvider { public function register(): void {} public function boot(): void { Str::macro('randomSlug', function ($slug, $length = 6) { return Str::slug($slug . ' ' . Str::random($length)); }); } } Here's how to use the custom helper in a controller. <?php namespace App\Http\Controllers; use Illuminate\Support\Str; class TestController extends Controller { public function test() { return Str::randomSlug('Hello World'); } } The output will be like this: hello-world-tn8hfd Using macros, we can create custom methods on Laravel's string helper to make string manipulation easier in a Laravel application.  ( 3 min )

Polymorphism in PHP is an object-oriented programming concept that allows different classes to be treated through a common interface or parent class. It enables you to call the same method on different objects, each responding in its own way. This promotes code flexibility and scalability, making it easier to extend functionality without modifying existing code. A common example is having multiple classes like PdfExporter, CsvExporter, and XmlExporter all implementing an export() method from a shared interface — allowing you to work with any of them interchangeably in your code. Do you find it makes your codebase more maintainable — or more complex? Have you ever replaced polymorphism with simpler conditional logic for readability? In Laravel (or other PHP frameworks), where have you found polymorphism most useful? Do you think polymorphism is overused in some PHP projects, or is it underutilized compared to what it can offer?

In part 1 I proposed a simple modification to Google’s Multi-Window Multi-Burn Rate alerting setup and I showed how this modification addresses the cases of varying-traffic services and typical latency SLOs. While my proposed solution was simply to alert on the error budget instead of the error rate, in this part I will show how we can still alert on the error rate but do it correctly. More importantly, the novel error-rate-based alert I will develop will expose a dynamic time-dependent burn rate expression which in contrast to Google’s static one leads to built-in compatibility to varying-traffic services. A certain disadvantage in my proposed solution in part 1 is that the metric which it alert on is the error budget while the metrics we care for when implementing SRE are the SLIs (or th…  ( 8 min )

🧠 What Is Lazy Loading? 💡 Key Benefits 🛠️ How to Implement Lazy Loading in React import React, { lazy, Suspense } from 'react'; const LazyComponent = lazy(() => import('./LazyComponent')); function App() { return ( ); } 2.Route-Based Loading (React Router) import { BrowserRouter as Router, Routes, Route } from 'react-router-dom'; import { lazy, Suspense } from 'react'; const Home = lazy(() => import('./Home')); const ImagePage = lazy(() => import('./Image')); function App() { return ( } /> } /> ); } 3.Image & Component Libraries import LazyLoad from 'react-lazyload'; 4.Dynamic Imports with Buttons or Interactions const LazyProfile = lazy(() => import('./LazyProfile')); function App() { const [showProfile, setShowProfile] = useState(false); return ( setShowProfile(!showProfile)}> {showProfile ? 'Hide' : 'Show'} Profile {showProfile && ( )} ); } ✅ Best Practices Lazy-load only non-critical code - e.g., modals, routes, images. Always pair with fallback UI using Suspense. Consider preloading components likely to be used soon. Handle errors gracefully with Error Boundaries. Test on real devices and low-bandwidth connections. 🔚 Final Words Done right, lazy loading reduces initial payloads, improves perceived responsiveness, and keeps your app scalable. Done poorly, it adds complexity and brittle flows. Try adding a lazy-loaded route or image to your next React build - it could save your user seconds of load time.  ( 3 min )

Recently, I saw an announcement right here on dev.to about the Build Games with Amazon Q CLI challenge promoted by AWS. The idea is simple: use Amazon Q's AI to build a game, share how you did it, and if you're among the first 2,000 valid participants, you get an official Amazon Q t-shirt. I had already done some tests with Amazon Q before, so when I saw this challenge, I realized it was the perfect opportunity to turn an experiment into something more fun — and still walk away with a new t-shirt in the end. In fact, I had already participated in a previous initiative and shared my experience in this article here on dev.to. Instead of using just the terminal, I chose to use the official Amazon Q extension for Visual Studio Code, which makes the experience much smoother. With it, you can ta…  ( 4 min )

Yesterday, I was really excited since joining the course, wondering when we would attend a hackathon because my brother had told me that if a hackathon happens, don't miss it, attend it, you'll get good experience and learn something new. Then yesterday, I got a chance to attend hackathon. So, I woke up early in the morning and got ready to go. But suddenly, I got food poisoning, so I couldn't attend. I felt really bad. Some of my friends attended and later shared their experiences, which made me feel even worse. The day before, I had eaten chicken fried rice at a hotel in Chennai, and it didn’t suit me. My parents scolded me and told me that hereafter, I shouldn’t eat non-veg in Chennai. I spent half of the day feeling upset, then I slept well in the afternoon. In the evening, I went to the temple, then visited my grandmother’s house, had dinner there, and slept... --> That’s how my day went:)  ( 3 min )

https://github.com/CampbellSoftware/Tardigrade Hello. I am Grayson. I recently built a programming language I call Glowscript. It doesn't have a compiler yet, but runs in a tkinter script. Here is how you can use Glowscript for sorting and messing with data! PRINT Hello World Let's break it down. The PRINT function prints Hello World onto the terminal. Pretty straightforward! SET x Hello SET y World PRINT x y Let's break it down. SET sets two variables named x and y with values "Hello" and "World". Then, PRINT prints them out. SET x 0 PLUS x 1 PRINT x LOOP 2 5 Let's break it down. SET sets x to 0, and plus adds 1 to x. PRINT prints x to the console. The LOOP function goes to line 2 5 times. In other words, every time you hit LOOP, it's counter, 5, goes down by 1, and once the counter reaches 0, LOOP does nothing. If you want to learn Glowscript, go to https://github.com/CampbellSoftware/Tardigrade now!  ( 3 min )

When the CDN Blinks: Endpoint Obfuscation, TTL Conflict, and Behavioral Web Architecture By Tyler Johnston-Kent (Formant) Computational Behavioral Analyst • Indie Systems Engineer • Firebase Web Architect I built a modular, fast-loading, secure portfolio and CMS system entirely from scratch — no frameworks, no CMS, no dependencies. Along the way, I unintentionally triggered a CDN cache anomaly involving Firebase Hosting and Cloudflare, driven by endpoint obfuscation and honeypot logic. This is a case study in how behaviorally-aware web design can expose CDN TTL mismatches, detect botnet patterns, and passively observe spoofed access without intrusive fingerprinting.

Today's Task: Photo Layout and Minor Adjustments Today I worked on the photo layout for one of the sections on my LP. It was mostly about placing images and making the surrounding design elements align visually. But here’s the thing: I started laying things out without a clear, defined goal or a vivid end image in mind. I just had a general feeling, maybe something like this and went from there. Design Fatigue, or Just a Weak Idea? After spending so long on the same page, I started losing perspective. Is this layout actually good? Or am I just getting used to it? I finished a version of the section, but I couldn’t shake the feeling that it’s… just okay. Not bad, but not memorable either. And that’s a problem. If It Doesn’t Move Me, It Won’t Move the User One thing I’ve been thinking about is this: If the creator doesn’t feel anything while making it, how can we expect the viewer to feel something or take action? That’s the scary part about visual design. It's not enough for it to function; it has to connect. Tomorrow's Focus: Figure Out Why Instead of tweaking the layout endlessly, I’ll take a step back tomorrow. I want to understand why this layout doesn’t feel right: Is it the lack of contrast? Are the images too weak or generic? Is the hierarchy unclear? Am I trying to say too much with too little? I’ll try to write down a few specific reasons, no matter how small, and build from there. Design isn’t just about moving elements around. It’s about making decisions with emotion and clarity. Today I moved pieces. Tomorrow I’ll try to move meaning.

ASGI: Beyond the Web – A Production Deep Dive Introduction Last year, a seemingly innocuous deployment of a new microservice responsible for real-time feature flagging triggered a cascading failure across our core platform. The root cause wasn’t a code bug in the feature flag logic itself, but a subtle deadlock within the ASGI server handling the persistent WebSocket connections. The server, under sustained load, was exhausting its event loop resources, leading to unresponsive services and ultimately, a partial outage. This incident highlighted a critical gap in our understanding of ASGI’s intricacies and the importance of careful resource management in async Python applications. This post aims to share lessons learned from that incident and provide a comprehensive, productio…  ( 7 min )

Oi, gente! 👋 Quero compartilhar uma ferramenta que conheci recentemente e tem me ajudado demais a criar laboratórios para estudar Linux: o Vagrant. Basicamente, o Vagrant automatiza a criação e o gerenciamento de máquinas virtuais. Mas atenção: ele não cria a VM sozinho — ele precisa de um provedor para isso (tipo VirtualBox, VMware, Hyper-V, Docker...). Para este exemplo, vou usar o VirtualBox, e todos os comandos foram feitos pelo PowerShell, no Windows mesmo. Primeiro, baixe e instale essas duas coisas: VirtualBox Vagrant Depois que instalar tudo, abra o PowerShell (pode usar o atalho Win + S, digitar "powershell" e abrir como administrador). Escolha onde você quer criar sua máquina. No meu caso, usei meu segundo disco (D:), então entrei na pasta com: cd D:\labs Aqui dá para seguir do…  ( 3 min )

Diving Deep into Node.js dgram: Production UDP for the Pragmatic Engineer Introduction We recently encountered a challenging scaling issue with our internal event notification system. Built as a REST API, it was struggling to handle the sheer volume of low-latency, one-way notifications required by our microservices architecture. Each service needed to broadcast events (e.g., “order created”, “user updated”) to interested subscribers without requiring a response. Polling was unacceptable due to latency and resource consumption. WebSockets were overkill for this simple broadcast pattern. This led us to revisit UDP and Node.js’s dgram module. This isn’t a “first look at UDP” post; it’s about how to leverage dgram in production Node.js systems where reliability, scalability, a…  ( 7 min )

Proxy: A Deep Dive into Enterprise Networking Introduction Last year, a critical production outage at a major financial institution stemmed from a misconfigured reverse proxy handling TLS termination for a core banking application. The proxy, overwhelmed by a sudden spike in legitimate traffic during a flash sale, began dropping connections, triggering cascading failures across dependent microservices. The root cause wasn’t a DDoS attack, but a lack of proper connection queue tuning and insufficient resource allocation on the proxy server. This incident, and countless others, underscore the critical role proxies play in modern network infrastructure. Proxies are no longer simply about circumventing firewalls or caching web content. They are foundational components in hybrid/mu…  ( 7 min )

Hello, folks! 👋 Vagrant. At its core, Vagrant automates the creation and management of virtual machines. But here's a crucial point: it doesn't create the VM on its own. It needs a provider to do that (like VirtualBox, VMware, Hyper-V, Docker, etc.). For this example, I'll be using VirtualBox, and all commands were executed in PowerShell on Windows. First things first, download and install these two: VirtualBox Vagrant Once everything's installed, open PowerShell. You can use the Win + S shortcut, type "powershell," and run it as an administrator. Choose where you want to create your virtual machine. In my case, I'm using my second drive (D:), so I navigated to the folder with: cd D:\labs You have two paths here. If you want to get straight to it, you can use: vagrant init centos/7 This…  ( 4 min )

Static Methods in JavaScript: Beyond the Basics Introduction Imagine you’re building a complex data visualization library for a financial trading platform. Users need to perform a variety of statistical calculations on time-series data – moving averages, standard deviations, correlation coefficients. Each calculation requires a specific algorithm, but doesn’t inherently belong to any particular instance of a TimeSeries object. Attaching these calculations as instance methods would be semantically incorrect and lead to unnecessary object creation and method lookup overhead, especially given the high-frequency nature of trading applications. This is where static methods become invaluable. They provide a clean, performant, and logically sound way to encapsulate utility function…  ( 7 min )

I have started to create a new open source project called EXSQL, which is a direct improvement to SQL, adding more modern enhancements and better syntax for complex applications. Enhanced and eXtended Structured Query Language is actually a transpiler (like JSX), which seeks to improve SQL by simplifying tasks and improving the syntax, such as inheritance in databases, making it a rather complicated and exhausting task, instead, thanks to EXSQL we could do something like “SUBTYPE OF” in a CREATE TABLE and it would generate all the necessary logic for the database but we would be using EXSQL to do everything. Right now I just did something simple (and not working) with python and Lark and created the repository where the project will be saved. I'm currently looking for feedback and help to carry out the project. Github Repository: https://github.com/Greem3/EXSQL  ( 3 min )

You arrive on-site, but the specific model's documentation is outdated, incomplete, or simply unavailable offline. Precious time is wasted searching for the right information, potentially delaying the repair, frustrating the customer, and impacting your company’s bottom line. This scenario, unfortunately, is all too common. In today’s fast-paced, digitally-driven world, access to accurate, up-to-date documentation is critical – not just for field service, but across every facet of an organization. Businesses are increasingly adopting cloud-native applications, embracing zero-trust security models, and navigating the complexities o…  ( 10 min )

Subnetting: Beyond the Basics - A Production-Grade Deep Dive Introduction I was on-call last quarter when a cascading failure hit our primary data center. The root cause? A misconfigured subnet mask on a newly provisioned Kubernetes cluster, leading to overlapping IP ranges with our existing monitoring infrastructure. This seemingly simple error brought down critical alerting, obscuring the initial outage and significantly extending our MTTR. This incident, and countless others throughout my career, hammered home the critical importance of meticulous subnetting. In today’s hybrid and multi-cloud environments, subnetting isn’t just a foundational networking concept; it’s the bedrock of scalability, security, and operational efficiency. It impacts everything from VPN connectiv…  ( 7 min )

EventEmitter: Beyond the Basics in Production Node.js Introduction Imagine a distributed system processing financial transactions. A critical component, the “Fraud Detection Service”, needs to notify multiple downstream services – Risk Assessment, Compliance, and User Notification – immediately when a potentially fraudulent transaction is identified. Direct synchronous calls introduce unacceptable latency and tight coupling. Asynchronous messaging is essential, but a simple queue isn’t enough; we need a flexible, in-process event dispatch mechanism to handle varying downstream requirements and potential failures. This is where EventEmitter shines, but its power is often underestimated and misused in production environments. This post dives deep into practical EventEmitter u…  ( 6 min )

The way I work as a software engineer has changed — and I didn’t exactly plan for it. A few years ago, my day was mostly about implementations. Writing boilerplate, stitching things together, obsessing over the finer points of state management or input validation. But with the rise of AI tools — not just code assistants, but a growing ecosystem of intelligent helpers — something shifted. I found myself writing fewer lines of code, and instead spending more time designing, prototyping, and exploring ideas at a higher level. Today, most of what I do is closer to rapid architecture and experimentation. I move fast — spin up MVPs, test proof of concepts, iterate, throw things away, rebuild. It’s liberating. But it introduced a new kind of bottleneck I wasn’t expecting: Almost everything I buil…  ( 9 min )

Been noticing a pattern lately. The prompts that actually work are nothing like what most tutorials teach. Let me explain. The disconnect Clear role definition ✓ Detailed instructions ✓ Examples provided ✓ Constraints specified ✓ Still got mediocre outputs. Sound familiar? What's actually happening The best performing prompts don't just give instructions. They create what I can only describe as "thinking environments." Here's what I mean: Traditional approach Do this Then that Output in this format What actually works Multiple reasoning pathways that intersect Contexts that allow emergence Frameworks that adapt mid-conversation Think of it like the difference between: Giving someone a recipe (traditional) Teaching them to taste and adjust as they cook (advanced) A concrete example Version …  ( 7 min )

Transforming Audio into Action: A Deep Dive into Google Cloud Speech-to-Text The modern enterprise is awash in audio data. From call centers handling thousands of interactions daily to IoT devices capturing environmental sounds, the ability to understand spoken language is becoming critical. Manually transcribing this data is costly, time-consuming, and doesn’t scale. Consider a global logistics company like DHL, needing to analyze driver communications for safety and efficiency. Or a healthcare provider, wanting to automatically document patient-doctor conversations for improved record-keeping and compliance. These scenarios demand automated, accurate, and scalable speech recognition. Google Cloud Speech-to-Text API provides precisely that, and its adoption is accelerating alongside t…  ( 9 min )
